An NMOS transistor is operating at the edge of saturation with an overdrive voltage VOV and a drain current ID. If is VOV is doubled, and we must maintain operation at the edge of saturation, what value of drain current results?

An NMOS transistor is operating at the edge of saturation with an overdrive voltage VOV and a drain current ID. If is VOV is doubled, and we must maintain operation at the edge of saturation, what value of drain current results?

(a) 0.25ID

(b) 0.5ID

(c) 2ID

(d) 4ID

I had been asked this question during an online interview.

This question is from MOSFETs Current-Voltage Characterisitcs in section MOS Field Effect Transistors (MOSFETs) of Electronic Devices & Circuits
