What are the features of a voltage follower circuit and what is its application?

Answer: The important features of the voltage follower circuit are as follows-

  • Closed loop voltage gain is equal to 1, i.e output is equal to input with no phase shift.
  • Very high input impedance.
  • Very low output impedance.
  • Large bandwidth.

Application- Voltage followers are placed between two networks to reduce the loading on the first network. This is due to the high input impedance offered by the voltage follower.
