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].
