In voltage follower, an input is equal to output. So voltage follower required single op-amp.

Here we use the concept voltage follower completely?

Surya said:   7 years ago
It is a buffer. Because the output follows the input voltage. (it's also called voltage follower).

When vi = vo, it is a voltage follower with Beta = 1 (unity gain).

Only one op-amp is required.

gain is 1 so that Av=Vo/Vin =1 so Vout=Vin

Use non inverting op-amp with output terminal shorted to inverting input of op-amp it behaves as unity gain amplifier i.e., vo = vi ;.

Mallik said:   1 decade ago
In op-amp Vout = Vin * gain ;

so if a gain of op-amp is 1 then Vout = Vin ;
this condition of an Op-amp is called Voltage follower .

It is called voltage follower op-amp.

For the buffer amplifier opamp output voltage is same as input voltage. Hence one opamp is required for amplification.
