Abstract
A system for reducing power loss in a switched-capacitor converter includes a first and second switched capacitor sub-converter each having a flying capacitor and a first, second, third, and fourth switching device. Each switching device is controlled by one of a first, second, third, and fourth clock signal. The first, second, third and fourth clock signals of the second switched capacitor sub-converter are inverted such that the first switched capacitor sub-converter operates during a first phase and the second switched capacitor converter operates during a second phase that is 1800 degrees out of phase from the first phase. The system also includes a resonant charge sharing portion for coupling a bottom-plate parasitic capacitance of the first switched capacitor sub-converter to a bottom-plate parasitic capacitance of the second switched capacitor converter.
