一种基于三比较器结构的低复杂度纯MOS滑动频率半数字Buck DC-DC变换器

Based on a triple comparator and several digital modules, a semidigital buck dc–dc converter is proposed and fabricated in 65-nm CMOS, for SoC power management. The switching frequency is automatically sliding from dozen kHz to sub-MHz for different load conditions. Experimental results show that the presented dc–dc converter has a high efficiency up to 93%, with an active area less than 0.03 mm2,...
