The small signal model for the common source FET can be used for analysing the basic FET amplifierconfigurations:(i)common source(CS),(ii)commondrain(CD) or source follower,and(iii)common gate(CG). The CS amplifier which provides good voltage amplification is most frequentlyused.The CD amplifier with high input impedance andnear-unity voltage gain is used as a buffer amplifier and the CG amplifier is used as a high frequencyamplifier.The small signal current-sourcemodel for the FET in CS configuration and the voltage source model can be derived by finding the Thevenin'sequivalent for the output part of amplificationfactor,drain resistance andtransconductance/mutual conductance of the FET.

How can transistors act as amplifiers or switches?
by creating two circuit loops
What does class D amplification mean?
Class-D amplification is where the amplifiers act as electronic switches.
What configuration will give both voltage and current gain simultaneously?
amplifiers operated with Common emmitter configuration for bipolar transistors , will give both voltage & current gain . Though equivalent fet & mosfet circuit topologies exist , these amplifiers operate more on signal voltage on input & the signal current is negligible compared to a bipolar transistor.
Within a CPU a transistor act as?
In a microprocessor, field-effect transistors behave as electrically-controlled switches.
Knee pont voltage- briefly distinguish?
The knee point voltage of a CT is the voltage at the "knee" of a I-V characteristic (if you increase voltage, and plot this voltage with respect to the current flow, you will see a logorithmic type response). The knee is usually specified as 10% distortion (ie, the voltage is 10% less than you would expect relative to the current flow). beyond the knee point, the CT is considered in saturation. This applies to amplifiers / transistors as well as CTs. Transistors used as ampifiers are operated in the "linear region", or the region below the knee point of that particular transistors I-V characteristic.
How can transistors act as amplifiers or switches?
by creating two circuit loops
What are the different components?
Transistors,diode,vacume tubes and amplifiers
What are power transistors?
Power transistors are transistors that are used in high-power amplifiers and power supplies.
Is it emitter-base junction should be reversed for both npn and pnp transistors acts as a amplifiers?
no, the emitter base junction should be foward for both npn and pnp to act as amplifiers.
What has the author Norm Dye written?
Norm Dye has written: 'Radio frequency transistors' -- subject(s): Power transistors, Radio frequency Amplifiers, Transistor amplifiers, Transistor radio transmitters
What are the different Active components?
Transistors,diode,vacume tubes and amplifiers
What are transistors used in?
Transistors are used in any electrical somponent including amplifiers, remote controls etc.
Does voltage drop have an important effect?
A: IN transistors it is very important since they themselves are voltage amplifiers
Why are npn transistors used more often than pnp transistors?
The primary reason that NPN transistors are used more often than PNP transistors is that they usually operate faster (at higher frequencies) because the mobility of the current carriers in NPN transistors (electrons) is much higher than that of the current carriers in PNP transistors (holes).
What has the author B Chirilov written?
B. Chirilov has written: 'Design of a low-noise, charge-sensitive preamplifier with field-effect transistors' -- subject(s): Amplifiers (Electronics), Field-effect transistors
Transistor works as an amplifier?
Yes, transistors can be used as amplifiers, but they are not limited to only this use (they are also used in logic circuits, for example).
Did second generation computer was electrical or mechanical?
Second generation computers used electronic transistors. A small number used magnetic amplifiers.
