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 controlĀ step responseĀ 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.
