Abstract

PURPOSE:To obtain the output signal with the correction given to the attenuation distortion at all times, by performing the sampling of the signal produced by the switched capacitor of the input step for only a fixed time within the holding time of the input signal and thus securing the correction for the aperture effect of a fixed time. CONSTITUTION:All capacitors excepting switched capacitor CA3 of the input step are actuated with clock signal phi1 or its signal phi1'. Then capacitor CA3 is actuated with the signal in which n-units of pulses of signal phi1 exist in sampling cycle 1/ fs. Thus the correction is given to the aperture effect within a fixed time by performing the sampling of the input signal produced by the switched capacitor filter by n-times with every cycle 1/fs. As a result, the output signal with the correction given to the attenuation distortion at all times can be obtained.
