Abstract
A switched capacitor amplifier includes a pair of output capacitors, providing high throughput suitable for pipestaged circuit applications. During operation, the amplifiers may generate an evaluation output once per clock cycle. During a first clock cycle, one of the two output capacitors holds an evaluation potential to be output from the amplifier and the second output capacitor both precharges and evaluates. During a second clock cycle, the roles of the output capacitors reverse and the second output capacitor holds the evaluation potential and the first output capacitor precharges and evaluates. The invention is suitable for use with a variety of amplifier topologies.
