The proposed circuit includes a negative voltage converter, a noninverting buck-boost converter working in discontinuous conduction mode (DCM), and a switching clock generator. Optimum load resistance is synthesized by the DCM buck-boost converter to achieve maximum power extraction, and system conduction loss is reduced by a novel arrangement of a current rectification diode within the buck-boost converter. This circuit is able to harness power from short-duration vibration and self starts up with a minimum 0.9-V input voltage. The proposed circuit has been implemented in a standard 0.18-μm CMOS process with 0.05-mm 2 active area and achieved a maximum power conversion efficiency value of 54%. © 2004-2012 IEEE.||Source Title:||IEEE Transactions on Circuits and Systems II: Express Briefs||URI:||http://scholarbank.nus.edu.sg/handle/10635/81908||ISSN:||15497747||DOI:||10.1109/TCSII.2012.2208672|
