Q. JFET Common Source Amplifier?
The common source configuration for a FET is similar to the common emitter bipolar transistor configuration, and is shown in figure. The common source amplifier can provide both a voltage and current gain. Since the input resistance looking into the gate is extremely large the current gain available from the FET amplifier can be quite large, but the voltage gain is generally inferior to that available from a bipolar device. Thus FET amplifiers are most useful with high output-impedance signal sources where a large current gain is the primary requirement. The source by-pass capacitor provides a low impedance path to ground for high frequency components of and hence AC signals will not cause a swing in the bias voltage.
Since the FET gate current is small we can make the approximations is = io and vs = - vas the source is positive with respect to the gate for reverse-bias. Since at low frequencies we can ignore the capacitor the source voltage is given by
