University of Michigan, Ann Arbor, MI Ultra-low power microsystems are gaining more popularity due to their applicability in critical areas of societal need. Power management in these microsystems is a major challenge as a relatively high battery voltage (e.g., 4V) must be down-converted to several low supplies, such as 0.6V for near-threshold digital circuits and 1.2V for analog circuits [1]. Furthermore, the small form factors of such systems rule out the use of external inductors, making switched-capacitor (SC) DC-DC converters the favored topology [2-4]. A key difficulty in SC-converters is their coarse output voltage resolution. This limits the ability of SC-converters to respond to battery voltage droop or to perform effective load regulation. For instance, in the case of ladder SC converter
