Spice programs are useful for switch capacitor simulations using raw switches and realistic op-amps. The following circuit is a design from elecfildes.com with the parameters given below.

The elecfildes program provides the circuit given in the post header. Using a voltage controlled spice switch, the dual phase circuit can be realized as below.

Using a Fast Fourier Transform of the output of the spice circuit, given an impulse as an input, the frequency response can be shown as in the figure below.
