Abstract :
A modified parallel realization for switched capacitor filters is presented. It is shown that in this modified parallel realization the error in the frequency response due to capacitor value changes is a function of the parameters. Accordingly, this error can be made less than error produced by cascade realization through proper choice of such parameters
