ABSTRACT:
A method of switching a switched-capacitor circuit to reduce signal-dependent distortion resulting from the switching operation. Two single-pole, double-throw switches in the array, having the switched capacitor coupling between to the common terminals thereof, are alternately switched without the use of an intermediate (no-make) state.
