Abstract
Conference Title: 2018 IEEE 61st International Midwest Symposium on Circuits and Systems (MWSCAS) Conference Start Date: 2018, Aug. 5 Conference End Date: 2018, Aug. 8 Conference Location: Windsor, ON, Canada This paper proposes a complementary topology for Switched-Capacitor (SC) DC-DC converter to enhance the dynamic response. For battery charging unit with faster charging time requirement, one of the major restrictions comes from the equivalent output resistance of the SC DC-DC converter. By connecting one completely symmetric SC converter as complementary topology with the original single converter, the proposed SC DC-DC converter topology decreases the equivalent output resistance down to half. Simulated in 0.13-$\mu$m standard CMOS process, the simulation results show that this complementary SC converter gains faster dynamic response, shorter charging time, and higher energy-conversion efficiency.
