Field Effect Transistors (FET)

Q1: The common-source JFET amplifier has:

A a very high input impedance and a relatively low voltage gain

B a high input impedance and a very high voltage gain

C a high input impedance and a voltage gain less than 1

D no voltage gain

ANS:A - a very high input impedance and a relatively low voltage gain

According to the given question, a common-drain JFET amplifier since a common-source JFET amplifier that has a medium input impedance with a medium voltage gain.
