Question

For amplifier biased to operate with an overdrive voltage of 0.5V, and disregarding the distortion caused by the MOSFET’s square-law characteristic, what is the largest amplitude of a sine-wave voltage signal that can be applied at the input while the transistor remains in saturation?

(a) 1.61 V

(b) 1.5 V

(c) 0.11 V

(d) 3.11 V

The question was posed to me in homework.

My enquiry is from MOSFET in Amplfier Design topic in section MOS Field Effect Transistors (MOSFETs) of Electronic Devices & Circuits

Answer 1

Correct answer is (b) 1.5 V

Explanation: Use the standard mathematical formula to obtain the result.
