Hi all,
I have a quick question. We all know how an opamp voltage follower works, but I am wondering since all the close loop feedback is negative to stablize the system, and keeps it from oscillating, but what about a positive feedback voltage follower. Is there any difference between the negative feedback voltage follower and a positive feedback voltage follower, and will the positive feedback voltage follower oscillate or become unstable?
Thanks for the help.
