Abstract

The present disclosure provides an asymmetric switching capacitor regulator that is capable of providing an output voltage, covering a wide voltage range, with a high efficiency. The disclosed switching capacitor regulator is configured to generate a wide range of an output voltage by differentiating a voltage across one or more switching capacitors from a voltage across the rest of the switchingcapacitors in the switching capacitor regulator.

Description

[0001] Cross References to Related Applications [0002] This application is based on 35 U.S.C. §119(e) claiming the benefit of the earliest filing date of U.S. Provisional Application No. 62 / 148,901, filed April 17, 2015, entitled "ASYMMETRICSWITCHING CAPACITOR REGULATOR," which is hereby incorporated by reference in its entirety . [0003] Statement Regarding Federally Sponsored Research or Development [0004] This invention was made with government support under 1353640 and 1447003 awarded by the National Science Foundation (NSF). The government has certain rights in this invention. technical field [0005] The present disclosure relates to asymmetric switched capacitor regulators. Background technique [0006] There is a strong need to reduce the size of electronic systems. Size reduction is particularly desirable in mobile electronics where space is scarce, but is also desirable in servers placed in large data centers, where it is important to compress as many serv...
