Q1: For an n-channel enhancement type MOSFET, if the source is connected at a higher potential than that of the bulk (VSB > 0), the threshold voltage VT of the MOSFET will

A remain unchanged

B decrease

C change Polarity

D increase

ANS:A - remain unchanged

VT depends upon MOSFET construction, hence it will Independent from MOSFET parameters.
