A)in the enhancement mode
B)in the depletion mode
C)in the saturated state
D)in the cutoff state

Question

Quizplus · Accepted Answer

When a negative gate-to-source voltage is applied to an N-channel MOSFET, it creates a depletion region at the surface of the semiconductor material under the gate oxide layer. This depletion region reduces the concentration of free charge carriers, thereby creating an insulating layer between the source and drain regions. Hence, the MOSFET operates in the depletion mode.
