Question

Why is collector emitter feedback better for linear circuits?

(a) Independent of β

(b) Dependent on β

(c) Highly predictable

(d) Not stable

I got this question during an interview.

The doubt is from Collector-Emitter Feedback Bias in section Transistor Biasing and Thermal Stabilization of Electronic Devices & Circuits

Answer 1

Right option is (b) Dependent on β

For explanation: Collector emitter feedback is better for linear circuits as compared to self – bias circuits as it is dependent on β. Voltage divider bias circuits are highly predictable whereas self – bias circuits are independent of β. Therefore, for a collector emitter feedback bias linear circuits are preferred.
