Question

Process transconductance parameter is directly proportional to

(a) Electron mobility only

(b) (Electron mobility)^-1 only

(c) Oxide capacitance only

(d) Product of oxide capacitance and electron mobility

I got this question in an internship interview.

I'd like to ask this question from MOSFETs Device Strucuture and Physical Operation topic in chapter MOS Field Effect Transistors (MOSFETs) of Electronic Devices & Circuits

Answer 1

Right answer is (d) Product of oxide capacitance and electron mobility

Explanation: It is the product of the electronic mobility with the oxide capacitance (F/m^2).
