Advantages and disadvantages of negative feedback amplifier

There are some advantages of negative feedback amplifier which are given below.

• The negative feedback has less frequency distortion.
• 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.
• The negative feedback reduces noise.
• Input and output impedance can be modified as desired.
• It can increase or decrease output impedance.
• It has higher fidelity i.e. more linear operation.

There are some disadvantages of negative feedback amplifier which are given below.

• Reduction in gain.
• It Increase output resistance in case of current shunt and current series feedback amplifiers.
