Abstract
This paper presents a fully integrated switched-capacitor dc-dc voltage regulator (SCVR) in standard 28 nm CMOS with a proposed regulation algorithm of multi-rate successive approximation (MRSA) and several conversion efficiency enhancement techniques. The proposed SCVR achieves 190 ps transient FoM with peak conversion efficiency of 83.7%@114.2 mA/mm2 and 110× supported loading range of 80 μA-8.8 mA. ? 2021 JSAP.
