摘要： A switched-capacitor circuit (10, 32 or 32A) samples a first signal (VIN + ) onto a first capacitor (C1 or CIN1) by switching a top plate thereof via a summing conductor (13) to a first reference voltage (VSS) and switching a bottom plate thereof to the first signal. A second signal (VIN -) is sampled onto a second capacitor (C3 or CIN3) by switching a top plate thereof to the second signal and switching a bottom plate thereof to the first reference voltage. After the sampling, the top plate of the second capacitor is coupled to the top plate of the first capacitor. The bottom plate of the second capacitor is coupled to the first reference voltage. The bottom plate of the first capacitor is coupled to a second reference voltage (VDD or VREF), to thereby cancel at least a portion of a common mode input voltage component from the first conductor (13), hold the sampled differential charge on the summing conductor and establish a predetermined common mode voltage thereon, and prevent the summing conductor from having a voltage which allows the leakage of charge therefrom. The switched-capacitor circuit may be a SAR, an integrator, or an amplifier.

摘要： A converter (10) for converting a first DC voltage (VDD) to a second DC voltage (VOUT) includes an output stage (40) for producing the second DC voltage (VOUT) in response to both the first DC voltage (VDD) and an output of an error amplifier (20). A sampling circuit (15) periodically energizes a voltage divider (R0,R1) by periodically coupling a first terminal thereof to the second DC voltage and periodically coupling an output (14) of the energized voltage divider to a feedback conductor (7) to refresh a feed back capacitor (C0) coupled between the second DC voltage and the feedback conductor. The feedback conductor is coupled to an input of the error amplifier.
