摘要：
We introduce the cyclic switched-capacitor dc-dc converter for single-input multiple-output power delivery. We focus on applications in stacked voltage domain (SVD)-based systems, and show that the cyclic architecture is robust to load current mismatches. We analyze such converters and give intuition for their power losses. We give experimental results from an SVD based power management integrated circuit (PMIC), designed and fabricated in a 130nm CMOS technology. The PMIC is a combination of a 2/3 stage reconfigurable cyclic SC dc-dc converter and a linear regulator. It can drive 3x3mA loads with the input supply voltage varying from 2.35-3.65V.
