Question

In a BJT, if the collector-base junction and the base-emitter junction are both reverse-biased, which region is the BJT operating in?

(a) Saturation region

(b) Active region

(c) Cutoff region

(d) Reverse active region

This question was posed to me in a national level competition.

My enquiry is from BJT Configuration in chapter BJT Biasing of Analog Circuits

Answer 1

Correct option is (c) Cutoff region

To explain I would say: If the collector-base junction and the base-emitter junction are both reverse-biased, then the BJT functions in the cutoff region of the output characteristics.
