Optimization of a multi-target voltages switched capacitor converter

Abstract

Abstract-In this paper, an efficient voltage scalable switched capacitor converter (SCC) for 1.1V battery-powered system is presented. The SCC employs a binary resolution technique to step-down the input voltage to a range of voltages, while keeping the efficiency high. An optimization strategy for designing multitopology SCC is presented to improve the effectiveness of the circuit and to preserve efficiency over large load voltages.
