There are some advantages of negative feedback amplifier which are given below,
The negative feedback reduces noise.
It has highly stabilized gain.
It can control step response of amplifier.
It has less harmonic distortion.
It has less amplitude distortion.
Input and output impedances can be modified as desired.
It can increase or decrease output impedances.
It has higher fidelity i.e. more linear operation.
It has less frequency distortion.
There are some disadvantages of negative feedback amplifier which are given below,
It Increase output resistance in case of current shunt and current series feedback amplifiers.
Reduction in gain.
