Abstract
The sensitivity properties of a class of switched-capacitor LDI ladder filter are investigated. It is shown that, because of the frequency variation of the termination in the equivalent circuit of such filters, the passband sensitivity property of the LC prototype filter is not retained. It is shown how the introduction of an extra switched capacitor at the input can result in lower passband sensitivities to the capacitance ratios
