Abstract :
A second-order stray-free circuit for the correction of amplitude deviations arising from the sample-and-hold effect in switched capacitor filters is proposed. The new circuit removes many of the shortcomings of a previously published first-order correction circuit, having improved correction accuracy together with reduced capacitance spread and total capacitance
