Abstract :
This paper presents a systematic approach to generate 2-phase switched capacitor DC-DC step-up converters with a given integer conversion ratio. The present method has a deterministic complexity and does not require any search. The generated charge pumps make use of theoretical minimum number of capacitors to achieve conversion ratios from 2 to 29, and almost theoretical minimum number of capacitors for all other conversion ratios. Design examples are presented to illustrate the proposed method.
