Abstract :
This paper describes a reconfigurable single-inductor triple-input triple-output regulator that is able to obtain power from three independent sources and provide multiple output regulations for energy-harvesting applications. A sub-threshold dual-mode controller can minimize power dissipation, avoid cross regulation between outputs, and provide predictable output noise spectrum. Implemented in a standard 0.35μm CMOS, the proposed regulator provides high power efficiency over a wide load range from 0.3mW to 42mW with the peak power efficiency of 88%.
