Question

The compensation techniques are used to_________

(a) increase stability

(b) increase the voltage gain

(c) improve negative feedback

(d) decrease voltage gain

The question was posed to me in unit test.

This is a very interesting question from Bias Compensation in division Transistor Biasing and Thermal Stabilization of Electronic Devices & Circuits

Answer 1

Correct option is (b) increase the voltage gain

Explanation: Usually, the negative feedback is used to produce a stable operating point. But it reduces the voltage gain of the circuit. This sometimes is intolerable and should be avoided in some applications. So, the biasing techniques are used.
