Cent percent feedback

Is it possible to make an amp with 100% feedback?

Any more negative feedback than say 20% and it turns into positive feedback!
Theoretically, 100% NFB would mean a gain of 1, so no longer an amplifier.

Yes, I have a Maplin mosfet amp which I converted to 100% feedback, it worked fine

"100% feedback" could mean so many different things (or nothing at all) that you'll have to be more specific...

And it becomes follower.

Yes, of course, then it becomes unity gain.

In fact, if inverting, you can have more than 100% feedback, go figure. 😱
