发明名称 Parasitic insensitive switched capacitor filter
摘要 A switched capacitor filter includes an amplifier in a feedback or feed-forward path thereof. The amplifier (A5, C6, S7,) has a gain dependent on the ratio of stray capacitances to the capacitors used in the filter so as to compensate for errors in filter characteristics which said stray capacitances would otherwise introduce.
