Hi all,
I heard about the asymptotic principle on feedback amplifiers in a YouTube video for the first time and I would like to know if someone else has also heard about to help me understand one thing.
The person who is talking about this, a professor I think, said the following for a simple opamp with the negative terminal connected to the output through a resistor and the positive terminal connected to a 1V battery:
To have a finite output voltage with an infinite gain the input voltage difference has to be zero.
And then he mention that this is the asymptotic principle of feedback amplifiers.
Does this make any sense? How come this?
BR.
