Question

In order to make an amplifier which of the following biasing technique is used more?

(a) Fixed bias

(b) Self bias

(c) Collector to base bias

(d) Emitter feedback bias

This question was addressed to me in examination.

This interesting question is from Emitter Feedback Bias topic in chapter Transistor Biasing and Thermal Stabilization of Electronic Devices & Circuits

Answer 1

Right option is (d) Emitter feedback bias

The explanation is: Since emitter feedback bias circuit, the output swing is very much stable and the design shows more stability to changes in temperature. Voltage divider circuit is the most used among all of the biasing technique because of its gain stability and impedance parameters.
