hello,
Fig.1 is the switched capacitor circuit and fig.2 is the clock signal.
the paper say that the error term induced by the finite opamp gain is proportionsl toA(-2), we call this gain-enhanced or gain-squaring,
can anyone tell me how to find the transfer funnction, thanks very much.
I think it is a filter design. You are writting the prenthesized clock phases trans-function. If don't ignore the gain error, I only get Vout/Vin=
(-C1/C2)/(1+(1+C1/C2)/A). I think you should better post your paper.

The answer maybe in this paper,but I cann't get this paper.
