MOSFETS Study guides, Class notes & Summaries

A D-MOSFET can operate in the - ANSWER Depletion-mode or enhancement- mode When an n-channel D-MOSFET has lo> loss, it - ANSWER is operating in the enhancement- mode

An Enhancement-mode MOSFET acts like a normally _______ switch. - ANSWER open What separates the metal gate electrode from the semiconductor substrate material in a MOSFET? - ANSWER an insulating layer In which MOSFET device is the channel already constructed to be the same doping as the source and drain? - ANSWER PMOS Depletion-Mode
