Abstract
Methods and systems related to capacitive voltage converters are disclosed. Such voltage converters may use a plurality of capacitors each having a first terminal and a second terminal. By periodically switching each first terminal between an input/supply voltage line and an output voltage line while also periodically switching each second terminal between the output voltage line and a reference voltage line, an output voltage having little ripple may be efficiently produced.
