This question already has an answer here:
I'm trying to understand some Op-Amp circuits given in a PDF by NI that shows a collection of useful opamp based circuit configurations.
I'm confused about this one that says Inverting amplifier with high input impedance. My doubt is what is the purpose of using a capacitor in the feedback loop of this circuit? Doesn't this circuit behave like an integrator with the capacitor in that position? How is it contributing to high input impedance? Please help!
