Question

Bias point is also referred by the name

(a) DC Operating Point

(b) Quiescent Point

(c) None of the mentioned

(d) All of the mentioned

I got this question in an interview for internship.

I'm obligated to ask this question of MOSFET in Amplfier Design in chapter MOS Field Effect Transistors (MOSFETs) of Electronic Devices & Circuits

Answer 1

Right choice is (d) All of the mentioned

The best I can explain: Bias point is called dc operating point as the MOSFET functions best at this point. Also since at the bias point no signal component is present it is called quiescent point (he reason why it is represented by the symbol ‘Q’)
