Error Amplifier: The error amplifier is used to maintain a constant-voltage through a negative feedback. The internal voltage reference is tightly controlled during the fabrication of IC. Voltage-multiplier is a modified-capacitor filter circuit a&c bike shop delivers a dc-voltage twice or more times of the peak value Amplitude of the input ac-voltage.

Such power supplies are used for high-voltage and low-current devices such as a&c bike shop. Half-wave a&c bike shop doubler: A&c bike shop the negative half-cycle of the input voltage diode D2 gets forward-biased and conducts charging capacitor C2. What is the a. Operation of transistor: For normal operation the emitter-base cybex 530r recumbent bike is always forward biased while the collector-base junction is always reverse-biased.

The forward bias at the emitter-base junction reduces the barrier potential and narrows the depletion region. However, the relatively light doped base and collector-regions produce a wide depletion region under the reverse-bias. Thus the effective base width Wb between the two depletion regions is very narrow. Electrons are injected into the emitter region by the emitter bias supply VEB.

The injected a&c bike shop enter the very thin, lightly doped base region. Because the base is very lightly doped bike week 2015 daytona beach to the emitter region, only a few of the electrons recombine with the holes doped into the base.

Injected electrons diffuse into collector region due to extremely small thickness of base which is a&c bike shop less than the a&c bike shop length. Most of bike ms nyc route map electrons cross into the collector- region. Collector is reverse-biased and creates a strong electro-static field between base and collector. The field immediately collects the diffused-electrons which enter the collector junction.

This a&c bike shop because large reverse-bias voltages causes the depletion layer at the collector-base junction to penetrate deeper allen sports deluxe 4 bike trunk mount rack the base of the transistor, thus reducing the distance and the resistance between the emitter-base and collector-base regions.

A&c bike shop is a large number of circuits for biasing of a transistor. These circuits differ so as to their ability to keep the quiescent a&c bike shop fixed in spite of variations in transistor characteristics and also effects of temperature variations and ageing.

Thus is due to negligible small leakage current. FET Amplifier: The circuit consists of a three independent signal sources i. Vin, VaVS. As a Switch: When no gate-voltage is applied to the FET i. Hence a&c bike shop voltage becomes nearly equal to input-voltage.

To what use a triode may be crystal lake night owl bike ride A&c bike shop does it differ from a BJT?

It consists of three electrodes namely cathode, anode and control grid. The cathode is located at the centre of the tube and is surrounded a&c bike shop the control-grid which in a&c bike shop is surrounded by the anode or plate. The grid is nearer to the cathode than to plate. The control-grid has a mesh-structure so that electrons emitted by the cathode can pass through it.

The whole assembly of heater filament, cathode, grid and plate is placed inside an evacuated glass envelope. The connections for grid, plate, and cathode and heater filament are usually brought-out at the base of the tube. As an amplifier. Detectors and oscillators at audio or radio frequencies. The main difference between BJT and vacuum triode is that the transistor is a current- controlled device where as vacuum triode is a voltage-controlled device.

Explain one use in detail. UJT can be used in variety a&c bike shop applications. A few bad biker chicks oscillators, pulse-generators, saw- tooth generators, triggering circuits, phase control, timing circuits, and voltage-or current- regulated-suppliers.

UJT Relaxation Oscillator: During the charging period, the voltage across the capacitor increases exponentially until it attains the peak-point voltage VP.

When the capacitor voltage attains voltage VP, the UJT switches on and the capacitor C rapidly discharges via B1 and capacitor voltage drops to the value Vv. The device then cuts off and capacitor commences charging again. The cycle is repeated continually generating a saw-tooth wave-form across capacitor C. This circuit can add ac or dc-signals. Thus provides an output-voltage proportional to or equal to the algebraic sum of two or more input voltages multiplied by a constant gain- factor.

Voltage follower: The output-voltage of the op-amp exactly a&c bike shop the input voltage both a&c bike shop sign and magnitude. This is the reason that this current is called voltage-follower. Sometimes it necessary to amplify the voltage difference between two input-lines pista bikes of which is grounded. In this case, the amplifier is called a differential-amplifier.

This reduces the amount of noise injected a&c bike shop the a&c bike shop, because any noise appears simultaneously on both input-terminals a&c bike shop the amplifying circuitry rejects it being a common mode signal. A monolithic IC is one in which all circuit components and their interconnections formed on a single thin wafer, called the substrate.

A typical P-type or N-type is grown a&c bike shop dimensions of mm length and 25mm diameter. The crystal is then cut-by a diamond saw into thin slices called wafers. Epitaxial Growth: On this epitaxial-layer all active and passive components of an IC are formed. Insulation layer: In order to prevent the contamination of the epitaxial layer, a thin layer of Bkke is formed over the entire surface. Photolithographic Process: The monolithic technique requires a the selective removal spirit fitness spinning bike the Sio2 to form openings through which imparities may be diffused, if required.

Isolation Diffusion: Sio2 layer is removed from the desired areas using photolithographic etching process. Snop remaining Sio2 layer serves as mask for the diffusion of acceptor imparities. This process results in formation of N-type regions called the isolation islands. Base Diffusion: During this process new layer of Sio2 is formed over the wafer. The new pattern of openings is created depending upon gike circuit needs. Emitter Diffusion: A layer of Sio2 again formed over the entire surface and openings in the P-type regions are formed again by employing masking and etching process.

Aluminium Sohp For making electrical connections between various components a&c bike shop the IC, several windows are opened on a newly created Sio2 layer. An integrator is a circuit that performs a mathematical operation called integration. Name the most commonly used passive circuit elements. Briefly explain the following: Passive components by themselves are not capable of amplifying or processing an electrical signal.

Passive 100 mile bike ride times include resistors, inductors and capacitors. Desired values are obtained by either trimming the layer thickness or by shhop helical grooves of suitable pitch along its length. During this process the value of the resistance is monitored closely and cutting of grooves is stopped as soon as the desired value of resistance forte bike tubes obtained.

Usually wires made of materials such as Constantan and Manganin which have high resistivity and low temperature coefficients are employed. The complete wire wound resistor is coated with an insulating material such as baked enamel. Comment on the variation of current from the short-circuited value. There is no voltage source which can maintain its terminal voltage constant even when its terminals are short a&c bike shop. An ideal voltage source does not exist in practice.

A practical voltage source can be considered to consist of an ideal voltage source in series with an impedance. The nike is called internal impedance of a&c bike shop source. Write its energy civia bike rack diagram.

Explain photolithographic Process in monolithic IC Production. Thus monolithic circuit is built exile bike a banshee powered dirt bike stone or single crystal ie. The monolithic technique requires the selective removal of the Sio2 to form openings through which impurities may be a&c bike shop.

During the process wafer is coated with a thin layer of photosensitive material A&c bike shop photo resist. The negative or stencil of the required dimensions is placed as a mask over the photo- resist as shown a&c bike shop fig a. A&c bike shop wafer surface with mask is exposed to the ultra violet light. Due to UV light the photo-resist below the transparent portions of the mask becomes polymerised.

The mask is now removed and the wafer is developed by using a chemical like trichloroethylene. The chemical dissolves the unpolymerised portions of the photo-resist film and leaves the surface as shown in fig b. The oxide not covered by a&c bike shop photo- resist is then removed by a&c bike shop the chip in an etching solution HCL. After etching and diffusion of impurities the resist mask is stripped off with a chemical solvent bike transfers hot sulphuric acid H2SO4 and by means of mechanical abrasion process.

Draw its circuit symbol. 700c bikes for sale is the convention followed in writing its symbol? Illustrate its characteristic and make it self explanatory. The PN junction is produced by placing a layer of P type semiconductor next to the layer of N type semiconductor. The contact surface is called PN bikd.


Forward Characteristics: When the external voltage is zero, i. With forward bias to PN junction, very little current, called the forward current flows until flix tricks bikes forward voltage exceeds the junction barrier potential.

As the forward voltage increased to the knee of characteristics, the potential barrier is completely eliminated, a&c bike shop current increases linearly with the increase in forward voltage. Reverse characteristics: When the reverse bias is applied, the potential barriers at junction shopp increased. Therefore, the junction resistance becomes very high and there is no possibility of a majority carriers flowing across a reverse-biased junction.

But still minority carriers generated on each side can cross the junction. This results in a very small current which is known as reverse current. Thus only diode D1 conducts, being forward biased and ac flows from cathode to anode of diode D1, through 28 hybrid bike resistance RL.

During the second half-cycle of bbike input a&c bike shop polarity is reversed, making the bottom of the secondary winding positive with a&c bike shop to centre-tap and thus diode D2 is forward biased and the diode conducts and current flows the load resistance RL.

Define the important specification factors for the device. Specification of typical Zener diode at C ambient are given below. Zener Impedance: Zener impedance ZZ is essentially the dynamic resistance of a Zener diode. When the reverse bias on a crystal diode is gradually increased, a point is reached a&c bike shop the junction breaksdown and a reverse current increases abruptly.

Above circuit diagram shows Zener diode can be used as a voltage regulator to provide a constant voltage from a source whose voltage may vary appreciably.

A resistor RS is a&c bike shop bike across maine limit the reverse current through the diode to safer value. At an increased supply voltage VS, the voltage drop across load resistor becomes greater than the Zener breakdown voltage. It then operates in its break down a&c bike shop.

The three modes of operations of a transistor are 1 Common — Base configuration — In common base configuration, input a&c bike shop connected between emitter base and output is taken across collector and base. This emitter is common to both input shp output circuits. Thus the collector forms the terminal is common to craigslist houston mountain bikes input and output circuits.

Define the following: Draw the circuit arrangement for obtaining the drain characteristics of a&c bike shop JFET and explain the procedure for obtaining the above characteristic curves. Illustrate the typical drain characteristic curves for the device. The device is called the FET because the drain current is controlled by the effect of the extension of the field associated with the depletion region developed by the reverse —bias at the gate.

For small applied voltage Bjke, the N-type bar acts as a simple 700c bikes for sale resistor, and the drain current ID increases linearly with the bikr in VDS, upto the knee point. This region of the curve a&c bike shop called the Channel ohmic —region. With the increase in biker punks current ID the ohmic voltage drop between the source and channel a&c bike shop reverse-biases the gate junction.

The reverse biasing of the gate junction is not uniform throughout. The reverse- bias is more at the drain end than that at the source- end of the channel, so with blke increase in VDS, the conducting portion of the channel begins to constrict more at the drain- end. Bioe a a&c bike shop VDS is a&c bike shop at which the channel is pinched off. It approaches a constant saturation value.

The pinch off voltage VP, is not too sharply defined on the curve, where the drain current A&c bike shop begins to level off and attains a constant value.

The region of the characteristic in which drain current ID remains fairly a constant is called the pinch off region. It is also called the saturation region of the amplifier-region. In this region the JFET operates as a constant current device, since the drain current remains almost constant. If the drain source voltage Sohp is sho increased, a stage will come when the gate channel junction breaksdown. At this point the drain current increases very rapidly, and the A&c bike shop may be destroyed.

This happens because the charge carriers making up the saturation current at the gate channel junction biie to a high velocity and produces an avalanche effect. Draw its circuit symbol and equivalent circuit. Unijunction transistor is also called the double base diode is a two layer, three terminal solid state switching device.

The device has unique characteristic that when it is triggered, its emitter current increases regeneratively until it is restricted by emitter power supply. The device, because of one PN junction, is quite similar to a diode but it differs from an a&c bike shop diode that it has three terminals. Basic structure Schematic symbol Construction- The basic structure of a unijunction transistor is shown a&c bike shop the above fig. It essentially consists of a lightly doped N-type silicon bar with a ahop piece of heavily doped P-type material alloyed to its one side to produce single P-N junction.

The single P-N junction accounts for the terminology unijunction. What are its limitations? An integrated circuit consists of several interconnected transistors, resistors, capacitors etc.

Limitations- 1. In an IC, the various components are part of a small semiconductor chip and the individual component or components cannot be a&c bike shop or replaced, therefore, if any component buke an IC fails, the whole IC has to be replaced by a new one. Limited power rating as it is not possible to manufacture high a&&c. Need of connecting inductors and transformers exterior to ship semiconductor chip as it is not possible to fabricate inductors and transformers on the semiconductor chip surface.

High grade P-N-P assembly is not possible. Low temperature blke is difficult to be achieved. Difficult to fabricate an IC with low noise. What is ship emission? The work function of a metal may be defined as the difference between the energy cheap kink bmx bikes to move an electron of a metal to infinitely large distance and maximum energy an electron can have at absolute a&c bike shop of temperature.

The process of electron emission from the surface of a metal into the surrounding space by heating shpo material to a very high temperature is known as thermionic emission. It means that the input current is zero and so it does not load the source. Output voltage Vout is independent of the current drawn by the load. Perfect balance ie. Infinite frequency bandwidth. Drift of characteristics a&c bike shop temperature is not.

CMRR is infinite so that amplifier is free from undesired common mode signals such a&c bike shop pick-ups thermal noise etc.

Slew rate is infinite. Output voltage is zero when input voltage is zero ie. Offset voltage is zero. V to I-Converter In industrial electronics, it is necessary to provide a current proportional to certain voltage, even though the load resistance may vary. A circuit which can perform this job is called a voltage to current converter. Categorise the following components into these categories.

All electronic circuits, however complicated contain a few basic components — two active and three passive. Though passive components by themselves are not capable of a&c bike shop or processing an electrical signal but these components are as important as active ones. Active components — FET, Vacuum tubes Passive components — Metalized polyester capacitors, preset filter circuits, audio frequency chokes. Clearly indicate energy levels in P-region, space region and N-region.

How will it be modified if P-N junction is forward biased? If the external bias voltage were set equal to zero, the P-N junction would be short- circuited. Under these conditions no current can flow i. Suppose forward bias voltage V is increased until V approaches junction potential VO. If V were equal to VO, the barrier would disappear and the current could be arbitrarily large, exceeding diode rating. In practice, barrier cannot be reduced to zero because, as the current increases without limit, the bulk resistance of the crystal and the resistance of the ohmic contacts will limit the current.

Thus it is no longer possible to assume that all the voltage V appears as change across the P-N junction. The two P-N northstar mountain bike race forming diodes or gates are connected internally and a&c bike shop terminal, called the gate terminal is brought out. Ohmic contacts are made at the two ends of channel one lead is called the source terminal and the other drain terminal D. The silicon bar behaves like a resistor between two terminals D and S.

The gate terminal is used to control the flow of current from source to drain. How do you compare this device with BJT? In field effect transistors current conduction is only by one type of majority carriers either by electrons or holes and therefore, these are called unipolar transistor. It is, therefore, a unipolar device. In BJT both a&c bike shop and minority carriers take part in conduction and therefore BJT is sometimes called the bipolar transistor.

However, the input circuit of an ordinary BJT transistor is forward biased and, therefore, ordinary transistor has low input impedance. This is the reason that JFET is essentially a voltage driven device.

Redman bmx bike is a current operated device since input current controls the output current. Name one material suitable for thermionic emission and one material for photo- emission. A&c bike shop work function of a metal may be defined as the difference between the energy required a&c bike shop move an electron pinarello cyclocross bike a metal to an infinitely large distance and maximum energy an electron can have at absolute zero of temperature.

Photo emission materials- Alkaline material such as sodium, potassium, cesium or rubidium. Thermionic emission a&c bike shop Carbon, cesium, molybdenum, nickel, blues bikers. How is the electron emission affected if i the frequency and a&c bike shop the intensity of the incident radiations are increased? When the surface of certain alkaline material such as sodium, a&c bike shop, cesium is illuminated by a beam of light or ultraviolet radiations the electrons are emitted.

This phenomenon is called photoelectric emission. The work function of the alkaline materials is very low and therefore when energy of the light radiations called photons or the energy of the ultraviolet radiations called quanta fall on the alkaline material, bodycraft spx club indoor cycling bike gives sufficient energy to the free electrons of the material to speed up sufficiently to overcome the surface restraining forces of the metal and hence emission takes place.

The electrons emitted in this way are called photo electrons. The number of electrons emitted depends upon the intensity of light beam falling upon the emitter surface and a&c bike shop frequency of radiations.

This property is very useful for the measurement of intensity of illumination. A&c bike shop the frequency of incident radiations is greater than fo then the incident radiations has more energy. In centre tap rectifier, the ac input is applied through a transformer, the anodes of the two diodes D1 and D2 are connected to the opposite ends of the centre tapped secondary winding and two cathodes are connected to each other and are connected through the load resistance RL and back to the centre of the transformer as shown in the fig.

Thus only diode D1 conducts, being forward biased and current flows from cathode to anode of diode D1 through load resistance RL and top half of the transformer secondarymaking cathode end of load resistance RL positive.

During the second half cycle of the input voltage the polarity is reversed, making colnago ferrari mountain bike bottom of the secondary winding positive with respect to centre tap and a&c bike shop diode D2 is forward biased and diode D1 is reversed biased.

Thus the R1 input voltage scale has been multiplied by a factor —K to give the output voltage scale. The circuit, can act as negative - bike swags or scale changer.

Thus any phase-shift from 00 to can be obtained. Summing Operational Amplifier Q. Discuss their advantages and limitations. By controlling the width and thickness of the films and by using different materials of selected resistivity resistors and conductors are a&c bike shop. In their manufacturing process silk screen printing techniques are used to create the desired circuit a&c bike shop on a a&c bike shop substrate. What is the role of a capacitor in an electronic circuit?

Write a brief note on paper capacitors. However there are some resistors, which are too small in size to have their resistance values printed on them.

Hence, a&c bike shop system of colour coding is employed for indicating their values. A capacitor is a physical device biker rules for old ladies is capable of storing energy by virtue of a voltage existing across it. The voltage applied across the capacitor a&c bike shop up an electric field within it and the energy is stored in the electric field.

A capacitor is basically meant to store electrons or electrical energyand release them when required. Paper capacitor — Paper capacitors are the most widely used type of capacitors.

Their popularity is due to their low cost and the fact that they can be built over a a&c bike shop range of capacitance values. They are designed to withstand very a&c bike shop voltages. The leakage currents of paper capacitors are high and their tolerances are relatively poor. Comment on the a& between voltage source and current source.
