Determine the conditions in which the MOSFET is operating in the triode region.

i. VGD > Vt (Threshold voltage)

ii. VDS > VOV

iii. ID ∝ (VOV – 0.5VDS)VDS

(a) i, ii, and iii are correct

(b) i and iii are correct

(c) i and ii are correct

(d) ii and iii are correct

This question was addressed to me in an interview for internship.

My enquiry is from MOSFETs Current-Voltage Characterisitcs topic in division MOS Field Effect Transistors (MOSFETs) of Electronic Devices & Circuits
