Which JFET amplifier configuration exhibits a very high input impedance and low output impedance?
A) common source
B) common gate
C) source follower
D) drain follower

Question

Quizplus · Accepted Answer

The source follower (also known as common drain) configuration exhibits a very high input impedance as the gate is connected to the input side and the output is taken from the source side. The source follower also has low output impedance as the load is connected between the source and ground. Therefore, the correct choice is C.
