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

|It is called voltage follower op-amp.|

|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 .

|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 ;.|

|gain is 1 so that Av=Vo/Vin =1 so Vout=Vin|
|Bharat Nimesh said: (Dec 18, 2015)|
|Only one op-amp is required.|
|Arya Mohan said: (Jun 28, 2016)|
|When vi = vo, it is a voltage follower with Beta = 1 (unity gain).|

|It is a buffer. Because the output follows the input voltage. (it's also called voltage follower).|
|Prashant Tyagi said: (Apr 21, 2017)|
|Here we use the concept voltage follower completely?|
|Pratigna said: (Mar 28, 2019)|
|In voltage follower, an input is equal to output. So voltage follower required single op-amp.|
