Abstract
This dissertation presents a study of power and area efficient voltage regulators. First, a dual-output switched capacitor voltage regulator (DOSCVR) is presented. In the proposed DOSCVR, by providing additional current paths to outputs with the crossing capacitor, power loss is reduced, while the power efficiency increases compared with the conventional approach that generates outputs using two single-output SCVRs. This increased efficiency of the proposed DOSCVR is achieved while maintaining the same total flying capacitance as the conventional approach, i.e., there is no area overhead penalty. Second, a study of multiple output SCVR (MOSCVR) is presented. Analysis and design method for MOSCVR are examined with output impedance analysis. The third study presents a reconfigurable area efficiency wireless power receiver and DC-DC converter. The proposed circuit reuses the RX coil as an inductor of DC-DC converter to save bulky magnetic component for area efficiency.
