Advantages and disadvantages of Negative feedback amplifiers

Some of the Advantages of negative feedback:

a) Input resistance increases

b) Output resistance decreases

c) Bandwidth increases

d) Non linear distortion decreases

e) Frequency distortion decreases

f) Sensitivity will be decreased

g) Gain stability

The main disadvantage of negative feedback is decrease in overall gain. The gain and feedback factor in an amplifier are often functions of frequency, so the feedback may lead to positive feedback.
