Abstract
This paper presents a modified Dickson converter to
achieve wide input range capacitive DC-DC converters. Several
implementations are carefully studied and compared, which shows
that the folding Dickson converter is the best choice, not only for
its reduced dynamic losses, but also for its very regular structure
and operation. Folding is achieved by merging the terminals of
two or more flying capacitors, creating one equivalent flying ca-
pacitor. In this design, a four stage folding Dickson conver
