Abstract
Hybrid switched-capacitor (SC) converters have
shown great promise in achieving high efficiency and power
density for dc–dc conversion. By combining an SC stage with
an inductor filter stage, benefits from both approaches can be
realized. In this work, a hybrid Dickson SC converter with a
4:1 native conversion ratio and regulated output voltage range
of 0.3–0.9 V from a 3.4 to 4.2-V lithium-ion battery and the
effective switching frequency of 1 MHz was implemented in 65-
nm bulk CMOS process. The c
