If a MOSFET is to be used in the making of an amplifier then it must work in
(a) Cut-off region
(b) Triode region
(c) Saturation region
(d) Both cut-off and triode region can be used
This question was addressed to me by my school teacher while I was bunking the class.
This interesting question is from MOSFETs Current-Voltage Characterisitcs in chapter MOS Field Effect Transistors (MOSFETs) of Electronic Devices & Circuits
