Abstract
A system for processing of signals with poles that are low in frequency includes a switched capacitor circuit that includes two switches connected to an input and an output of a switching capacitor (C), respectively, in an alternating manner at a selected switching frequency (f); and a filter capacitor connected between an input and the switched capacitor circuit. The filter capacitor and the switched capacitor circuit together function as a filter, thereby a pole frequency depending on a ratio of capacitance of the switching capacitor (C) and the filter capacitor, instead of an RC product.
