Hello, Could anyone please explain how this circuit works. I have looked at some standard op-amp circuits in a TI paper and this one is closest to a low noise differentiator. I find this in an audio amp circuit, amplifying an audio transducer. We are getting more noise at the output than we want, not sure the source. There is a sort of low pitch roaring and electronic switching noise. Any tips on what the gain of this circuit is and how to reduce it? FYI, I am an EE but not very versed on op amps.
