An n-channel enhancement MOSFET has VTH = 2 V. In the ideal long-channel model, if VGS = 5 V, the overdrive voltage VOV is?

A2 V
B3 V
C5 V
D7 V

Show AnswerHide AnswerReport an error

Correct Answer: B. 3 V

Explanation: MOSFET overdrive voltage is VOV = VGS - VTH = 5 - 2 = 3 V.

Reference: Standard MOSFET analysis: overdrive voltage
