Question

For a p channel MOSFET which of the following is not true?

(a) The source and drain are a p type semiconductor

(b) The induced channel is p type region which is induced by applying a positive potential to the gate

(c) The substrate is a n type semiconductor

(d) None of the mentioned

This question was posed to me during an internship interview.

I want to ask this question from MOSFETs Device Strucuture and Physical Operation in portion MOS Field Effect Transistors (MOSFETs) of Electronic Devices & Circuits

Answer 1

Right choice is (b) The induced channel is p type region which is induced by applying a positive potential to the gate

Explanation: The induced channel is p type region which is induced by applying a negative potential to the gate.
