Switched-capacitor (SC) converters have shown significant promise for monolithic integration in a variety of mobile computing applications due to the relatively high energy-densities of modern capacitor technologies and the emergence of deep-trench technology [1-4]. Compared to more traditional buck and boost topologies, the SC approach provides better utilization of active and passive components, and is especially favorable when using submicron or deep-submicron CMOS technology because low-voltage devices can be configured in cascaded or hierarchical structures to interface across wide conversion ratios [5]. Resonant switched capacitor (ReSC) converters can be considered an extension of the SC approach in that similar hierarchical and cascaded topologies are used, which provide comparable device utilization and scaling advantages. However, a small amount of magnetic energy storage is used to implement soft switching
