Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe following circuit is a voltage follower with Negative feedback.
The gain of Non-Inverting Amplifier is given by:
For voltage follower, Rf is 0
Hence gain (A) = 1
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
