Field Effect Transistors (FET) - Technical MCQs

Q1:

IDSS can be defined as:

A the minimum possible drain current

B the maximum possible current with VGS held at –4 V

C the maximum possible current with VGS held at 0 V

D the maximum drain current with the source shorted

ANS:C - the maximum possible current with VGS held at 0 V

IDSS (referred to as the drain current for zero bias) is the maximum current that flows through a FET transistor, which is when the gate voltage, VG, supplied to the FET is 0V.
