Can anyone help me with this problem? I'm trying to convert this circuit to the s-domain for further analysis but the capacitor is stumping me. It's a basic differential amplifier circuit, but there is a capacitor tied between the two op-amp inputs. I'm trying to figure out what the effect would be as the cap value changes.

R1 = Rf
R2 = Rg
Thanks!
