Is a voltage follower really simple?
« on: September 10, 2020, 12:21:56 am »
Hello I'm somewhat new to electronics and I've been designing a vocoder. Right now I've been working on a voltage follower that will provide the control voltage to my voltage controlled amplifiers in each frequency band. Is a voltage follower as simple as a rectifier? Or maybe a rectifier would lag the voltage too much? Let me know if the question is not clear.

rectifier is not a voltage follower at all! just google op amp voltage follower, any op amp should be able to take care of audio frequencies without an issue.

Let me know if the question is not clear.

A "voltage follower" can have various implementations but usually doesn't involve a "rectifier".

This page talks about an "envelope follower":

Is that what you are referring to?

Yes that is what I meant, sorry! Not a voltage follower, an envelope follower
