Question

In Miller’s theorem, what is the constant K?

(a) Total voltage gain

(b) Internal voltage gain

(c) Internal current gain

(d) Internal power gain

I got this question in a job interview.

My question comes from Low Frequency Response and Miller Effect Capacitance topic in chapter Transistor Frequency Response of Analog Circuits

Answer 1

The correct choice is (b) Internal voltage gain

Explanation: The constant K=V2/V1, which is the internal voltage gain of the network.

Thus resistance RM=R/1-K

RN=R/1-K^-1.
