	abstract = {<p>
	A device and method for hybrid feedback control of a switch-capacitor multi-unit voltage regulator are presented. A multi-unit switched-capacitor (SC) core includes a plurality of SC converter units, each unit with a capacitor and a plurality of switches controllable by a plurality of switching signals. Power switch drivers provide a switching signal to each SC converter unit. A secondary proactive loop circuit includes a feedback control circuit configured to control one or more of the plurality of switches. A comparator is configured to compare the regulator output voltage with a reference voltage and provide a comparator trigger signal. Ripple reduction logic is configured to receive the comparator trigger signal and provide an SC unit allocation signal. A multiplexer is configured to receive a first clock signal, a second clock signal, and the SC unit allocation signal and provide a signal to the power switch drivers.
