Question

What is the bias of a simplified CB short circuit current frequency response configuration?

(a) Reverse biased

(b) Forward biased

(c) Forward and reverse biased

(d) It is independent of the bias

The question was posed to me by my college professor while I was bunking the class.

The origin of the question is The CB Short Circuit Current Frequency Response topic in section High Frequency Transistor of Electronic Devices & Circuits

Answer 1

Correct option is (b) Forward biased

Best explanation: The CB short circuit current frequency response operates such that the input signal is applied to the emitter terminal and the output is taken from the collector terminal. The emitter current is also the input current, and the collector current is also the output current. The base – emitter junction is forward – biased.
