Enhancement type MOSFET cannot be operated in_____ mode.

• depletion

• enhancement

• Both A and B

• none

The enhancement MOSFET is _______

•  widely used in IC design

• Useful as a very good constant voltage source

•  Widely used because of easy in its fabrication

• Normally used as a MOSFET

In MOSFETs N-channel is more preferred than P-channel because

•   It is cheaper

• It is faster   

• It has better drive capability

• It has better noise immunity
