Field Effect Transistors (FET) - Technical MCQs
Q1: What is the input impedance of a common-gate configured JFET?A
very low
B
low
C
high
D
very high
ANS:A - very low Common gate FET configuration provides a low input impedance while offering a high output impedance. Although the voltage gain is high, the current gain is low and the overall power gain is also low when compared to the other FET circuit configurations available. |
