Question

What do the small signal parameters in a transistor circuit taking source resistance into account vary with respect to in the linear analysis?

(a) Load line

(b) Bias point

(c) Temperature

(d) Makes no difference

I have been asked this question in an online quiz.

This question is from Transistor Amplifier Response, Taking Source Resistance into Account topic in section High Frequency Transistor of Electronic Devices & Circuits

Answer 1

Right answer is (b) Bias point

Explanation: The small signal parameters in a transistor circuit taking source resistance into account vary with respect to the bias point in the linear analysis model. This occurs even in the linear region of the characteristic curve of the transistor.
