In this video, you will find a detailed discussion on the effect of negative feedback on amplifiers.

Negative feedback introduces the following modification of the amplifier characteristics.

Gain is reduced and stabilized w.r.t variations in parameters.

Reduction in nonlinear distortion.

Input and output impedance can be changed by a suitable feedback network.

Bandwidth of the amplifier increases and frequency distortion becomes less.

Phase distortion is reduced.

Noise level is lowered.

You will find the derivation for Input and output impedance of voltage series feedback amplifier.
