Abstract
An improved switch capacitor circuit includes a capacitor, a 1st voltage reference module, a 2 voltage reference module, and a plurality of switching elements. The capacitor is operably coupled via the plurality of switching elements to sample an input signal during a 1 interval of a sampling period and during a 2 interval of the sampling period to provide a representation of the input signal. The 2 reference module produces a 2 reference voltage that is representative of the common mode of the supply (e.g. V and V ). The 1 voltage reference module produces a 1 reference voltage that is representative of the common mode of the analog input signal. As such, the capacitor is charged during the 1 interval based on the 1 reference voltage and discharged during the 2 interval based on the 2 reference voltage.
