For MOSFET is to be used as a switch then it must operate in
(a) Cut-off region
(b) Triode region
(c) Saturation region
(d) Both cut-off and triode region can be used
I got this question in a job interview.
Enquiry is from MOSFETs Current-Voltage Characterisitcs topic in chapter MOS Field Effect Transistors (MOSFETs) of Electronic Devices & Circuits
