This paper proposes multiinput switched capacitor (SC) integrators required for realization of leapfrog SC filters exhibiting zero sensitivity at matching points. The signal flow graph-based simulation of an LC ladder filter built of proposed integrators shows that the filter exhibits zero sensitivity. Integrators are driven by a two-phase dock and, under certain conditions, are insensitive to parasitic capacitance. Furthermore, total filter capacitance generally is kept small. Computer simulation of lowpass and bandpass filters constructed of the proposed integrators illustrates their comparatively low sensitivity.
