Abstract

In one example, a method comprises alternately switching on a first switch connected in series with a capacitor and connected in parallel with a first capacitive element, and a second switch connected in series with the capacitor and connected in parallel with a second capacitive element. Aeries circuit with the first switch, the capacitor and the second switch may be coupled to supply nodes for receiving a supply voltage.
