10.3 A 94.2%-peak-efficiency 1.53A direct-battery-hook-up hybrid Dickson switched-capacitor DC-DC converter with wide continuous conversion ratio in 65nm CMOS
Owing to the need for low power consumption, portable and wearable electronics operate at low voltages, typically below 1V, with recent designs in near- and subthreshold operation resulting in voltages down to 0.3 to 0.5V. Meanwhile, voltage range of the most common energy source - the Li-ion battery - is 3 to 4.2V, motivating the need for compact power converters capable of large conversion ratio with wide and efficient voltage regulation.
