The input coupling capacitor is generally smaller on a CS amplifier than its equivalent BJT counterpart because
A)Rin is higher, compensating for the smaller C
B)the FET is a voltage- controlled device, so the extra charge is not needed
C)the input signal voltage is generally smaller
D)the frequency response is more important in BJTs than FETs

Question

Quizplus · Accepted Answer

The input resistance (Rin) of a FET is typically higher than that of a BJT, allowing for a smaller coupling capacitor (C) to achieve the same low-frequency cutoff.
