摘要：
A switched capacitor environment in which a feedback capacitor of a stage is flipped to be used as a sampling capacitor of the next stage. Due to such use of the feedback capacitor, the noise introduced by the stages is substantially reduced. Such switched capacitors can be used in analog to digital converters (ADC).
