Question

The saturation current of the MOSFET is the value of the current when

(a) The voltage between the drain and drain becomes equal to the overdrive voltage

(b) The voltage between the drain and drain becomes equal to the threshold voltage

(c) The voltage between the drain and drain becomes equal to the voltage applied to the gate

(d) The voltage between the drain and drain becomes equal to difference the overdrive voltage and the threshold voltage

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

This interesting question is from MOSFETs Device Strucuture and Physical Operation topic in division MOS Field Effect Transistors (MOSFETs) of Electronic Devices & Circuits

Answer 1

The correct answer is (a) The voltage between the drain and drain becomes equal to the overdrive voltage

Explanation: By definition of the MOSFET saturation current.
