ADVANTAGES OF VOLTAGE FOLLOWER

Voltage Follower

  • A voltage follower is an op-amp circuit whose output voltage is equal to the input value (it "follows" the input voltage).
  • As a result, a voltage-follower op-amp has a voltage gain of one and fails to improve the input signal.
  • The voltage follower does not offer attenuation or amplification; it only serves as buffering.
  • The input impedance of a voltage-follower circuit is quite high.
  • Because of this property, it is a common option in a wide range of circuits that require isolation between the input and output signals.
  • It is important to remember that Ohm's rule supports a voltage follower.

 

Advantages of Voltage Followers

  • Offers power and current gain.
  • Low output impedance for the circuit that employs the voltage follower output.
  • The op-amp consumes no current from the input.
  • Loading effects are avoidable.

 

Applications of Voltage Followers

  • Buffers for logic circuits.
  • Used in sample and hold circuits.
  • In the active filters.
  • Using a transducer in bridge circuits.
