Abstract

The common-mode voltage of a switched-capacitor system is controlled by determining a current common-mode voltage of the switched-capacitor system, converting (in a flow-through conduction cell) the difference between the current common-mode voltage and a desired common-mode voltage into a resultant current, and reinjecting this resultant current into the switched-capacitor system via a resistive path.
