Abstract
A fully integrated voltage doubler is presented. Using a 16-phase switching strategy, the output voltage ripple is reduced to less then 0.5% of the output voltage. To the author´s knowledge, the peak efficiency and nominal efficiency of this voltage doubler, respectively 82% and 79%, exceed the efficiency of any known fully integrated converter, inductive as well as capacitive. The converter is fabricated in a 130nm CMOS process.
