Abstract

This letter introduces the phase-merging turbo (PMT) technique, a method which significantly augments the output current capability of a continuous scalable conversion-ratio (CSCR) switched-capacitor voltage regulator (SCVR). The research also proposes a unique method for implementing communication-free ganging with these converters, enhancing their scalability across a wide range of power domain sizes. Fabricated using a 4-nm class CMOS technology, this study achieves a current density of 26 A/mm2 for monolithic capacitive voltage regulators, and a peak efficiency of 88.5%.
