Advantages and disadvantages of negative feedback amplifier

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.
  • It has less phase 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.
