Abstract
A novel switched capacitor gain stage uses a unique circuit design and clocking technique that reduces the component mismatch offset voltage and the clock-induced feedthrough offset voltage produced by the circuit. The total capacitance ratio between the input capacitors and the feedback capacitor necessary to achieve a desired total gain is also minimized.
