say I would need to find the gain (Vo/Vi) for a given circuit like this one with multiple op-amps.
I know how to find the gain for a simple circuit with a single op-amp, like an inverting circuit circuit would be -(R2/R1)Vin
But I can find the gain in those situations only because I know the gain formulas for those specific op-amps circuits. How can I determine the gain for unique circuits like this one?
I know for a start that the first op-amp is a voltage follower, so its output equals Vi, but that is about it... I am lost afterwards. I don't recognize any op-amp circuit on the right stage.
I am basically looking for a universal approach to calculating gain of op amps circuits
Thank you for your help!!
