Abstract
A method and apparatus for reducing settling time of a switched capacitor amplifier. The method includes disconnecting first and second capacitors from an amplifier. When the first and second capacitors are disconnected from the amplifier, they are charged by respective first and second input signals. The apparatus includes a plurality of sampling capacitors, each configured to sample a respective one of a plurality of signals during a sampling phase, an amplifier, and a plurality of decoupling switches configured to isolate the sampling capacitors from the amplifier during the sampling phase and to connect the plurality of sampling capacitors to the amplifier during the amplifying phase.
