Fully integrated high-voltage generators with optimized power efficiency

This paper describes how the power efficiency of fully integrated Dickson charge pumps in high-voltage IC technolo-gies can be improved considerably by implementing charge recycling techniques, by replacing the normal PN junction diodes by pulse-driven active diodes, and by choosing an appropriate advanced smart power IC technology. A detailed analysis reveals that the combination of these 3 methods more than doubles the power efficiency compared to traditional Dickson charge pump designs.
