Voltage Follower OPAMP or buffer Amplifier

OPAMP buffer or voltage follower is an opamp configuration whose gain is equal unity. Voltage follower is also known as unity gain amplifier, voltage buffer, opamp buffer, or an isolation amplifier. It is used to separate two circuits having the same voltage level but different impedance. In a voltage follower circuit output voltage and input […]
