A method is described for the extraction of capacitor values for switched capacitor (SC) networks which compensate for the effect of finite amplifier bandwidth in the design of SC networks using optimization. The finite bandwidths of the amplifier distort the response of the network from the required response. It is shown that by readjusting the poles and zeros of the transfer function, the required response can be accurately restored. The values of capacitances are extracted by running a number of parallel local optimizations, each starting from different random initial conditions, on a network of transputers. This method removes the possibility of an optimization being trapped in a local minimum and ensures the stability of the design network.
