Buffer stage amplifier

WebA voltage buffer, also known as a voltage follower, or a unity gain amplifier, is an amplifier with a gain of 1. It’s one of the simplest possible op-amp circuits with closed-loop feedback. Even though a gain of 1 doesn’t give … WebOne useful function of a buffer (voltage gain of 1) amplifier is to prevent interfering signals at stage 2 from propogating to stage 1 of a signal-processing chain. So, a buffer …
