  • Abstract
    A new design method for switched-capacitor filters (SCF) is presented. It is based upon an LU matrix decomposition technique and has the distinct advantage of producing SC filter realizations containing no delay free loops. These are formed traditionally by capacitors and opamps in leapfrog realizations. It is demonstrated that this feature should render reduced dependence of the filter response to nonideal effects such as finite amplifier GB and switch resistance. Results from realistic leapfrog and LUD SC filter realizations confirm this.
