How effective the gate-source voltage is controlling the drain current is referred to as _________.
A) pinchoff
B) saturation
C) transconductance
D) conductance

Question

Quizplus · Accepted Answer

The transconductance of a MOSFET determines how effectively the gate-source voltage can control the drain current. Saturation refers to the condition where the drain current has reached its maximum and is independent of further increases in gate-source voltage. Pinchoff is a term used to describe the region of the MOSFET channel where the current is very small due to a high electric field. Conductance is a measure of how easily current flows through a material and is not directly related to the effectiveness of gate-source voltage control.
