The body effect in an NMOS transistor generally causes threshold voltage magnitude to do what when source-to-body reverse bias increases?

AIncrease
BDecrease to zero
CRemain exactly unchanged
DBecome an AC frequency

Show AnswerHide AnswerReport an error

Correct Answer: A. Increase

Explanation: Increasing source-body reverse bias increases the threshold voltage required to form the inversion channel; this is the MOSFET body effect.
