Abstract:
A switched capacitive voltage converter for converting an input voltage (U.sub.i) between an input terminal (I) and reference terminal (RF) to an output voltage (U.sub.o) between an output terminal (O) and the reference terminal (RF), characterized in that the switched capacitive voltage converter comprises: a first capacitive element (C.sub.1); a second capacitive element (C.sub.2) coupled between the output terminal (O) and the reference terminal (RF); first switching means (S.sub.1) coupled between the input terminal (I) and a first electrode of the first capacitive element (C.sub.1); second switching means (S.sub.2) coupled between the output terminal (O) and the first electrode of the first capacitive element (C.sub.1); third switching means (S.sub.3) coupled between the output terminal (O) and a second electrode of the first capacitive element (C.sub.1); fourth switching means (S.sub.4) coupled between the second electrode of the first capacitive element (C.sub.1) and the reference terminal (RF); and fifth switching means (S.sub.5) coupled between the input terminal (I) and the second electrode of the first capacitive element (C.sub.1).
