Simulation of such circuits typically requires a transient analysis tool such as HSPICE. In order to obtain a frequency response of a switched capacitor circuit with such a tool, a transient analysis would be required where the time step is determined by the highest frequency and simulation time is determined by the lowest frequency.
This article presents a circuit simulator that can simulate switched capacitor circuits. The simulator uses graph topologies to perform time domain and frequenc
Switched capacitor circuits can also be used to realize circuits such as mixers, voltage controlled oscillators, signal processing circuits, etc. By their very nature, switched capacitor circuits are time varying. Simulation of such circuits typically requires a transient analysis tool such as HSPICE.
A tool that has been widely used to provide ac analysis of switched capacitor circuits is SwitCap, developed by Columbia University’s Department of electrical engineering. Certainly SwitCap has been a useful tool providing quick simulations of switched capacitor circuits in both time and frequency domains.

As the first step, an AC analysis of the switched capacitor amplifier circuit is performed in the frequency range to be used in the periodic steady state analysis of the circuit. The AC analysis is done to measure the -3dB corner frequency (ωc) of the amplifier. The input voltage source is specified as Vin =1mV AC at the input.
