Question

At ______________ the drain current is no longer related to the Vgs by square law relationship.

(a) When the temperature is high (around 700 Celsius)

(b) When temperature is very low (around -50 Celsius)

(c) Velocity saturation

(d) None of the mentioned

I had been asked this question in an online quiz.

I'd like to ask this question from The Body Effect in section MOS Field Effect Transistors (MOSFETs) of Electronic Devices & Circuits

Answer 1

Correct choice is (c) Velocity saturation

To explain: At velocity saturation the current depends linearly on the Vgs.
