The above circuit is a voltage follower with Negative feedback. A voltage follower is an op-amp circuit whose output voltage straight away follows the input voltage. i.e. output voltage equivalent to the input voltage.
Characteristic of voltage follower:
- High input impedance
- Low output impedance
- The loading effect can be avoided
- Opamp takes zero current from the input
- Provides power Gain & current gain but voltage gain unity
