ok so if we have an amplifier with direct negative feedback we have a voltage follower
if we put a resistor between that inverting input pin and ground, we can do these things:
if we put another resistor between the output and the inverting input we can adjust the gain
if, instead, we use a capacitor between the the output and the inverting input we can get an integrator
im looking at a schematic for a Mass Flow Controller right now that, instead of that resistor or that capacitor between the output and the inverting input, we have both a resistor and a capacitor, in parallel, between the output and the inverting input. what does that do and how can i measure what it does?
