Trying to build a multi-stage 120kHz bandpass filter... decided to
use multi-feedback topology...
Seems that it amplifies the desired signal alright, but ends up full-
swing output (after just one stage) and since it's inverted, the full-
swing output feedback ends up cancelling out the input and it
collapses back on itself.
I'm no op-amp expert but am ernestly trying to learn.... and I'm
stumped on how to procceed...
thanks!
