Can we consider differential amplifier with unity gain as buffer?

According to me, buffer is nothing but o/p connected to i/p through -ve terminal. But in differential amplifier I am using Rs and Cs in feedback.

thanks in anticipation.
 

Hi,
You can use an differential amplifier as a Buffer....

And the Rs and Cs are used for Phase margin and stability of your Diff-Amp...
Diff-Amp is a simple form of an Op-amp..

Thanks..
