Abstract
A switched capacitor circuit utilizes a pair of serially connected differential amplifiers that have plus inputs, minus inputs, plus outputs, and minus outputs. Feedback to the plus/minus inputs is in a first configuration relative to the output of the pair of differential amplifiers in a sampling mode and a second configuration in a hold mode. Similarly, the plus/minus inputs relative to the plus/minus outputs of the serially connected differential amplifiers is reversed between the sampling and hold modes.
