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). The voltage converter comprises only two capacitors (C.sub.1, C.sub.2) and five switches (S.sub.1 -S.sub.5). The first (S.sub.1) and the second switch (S.sub.1) are coupled in series between the input terminal (I) and the output terminal (O). The third (S.sub.3) and the fifth (S.sub.5) switch are also coupled between the input terminal (I) and the output terminal (O). The first capacitor (C.sub.1) is coupled in series between a node common to the first (S.sub.1) and the second (S.sub.2) switches and a node common to the third (S.sub.3) and the fifth (S.sub.5) switch. The fourth switch (S.sub.4) is coupled between the node common to the third (S.sub.3) and the fifth (S.sub.5) switch and the reference terminal (RF). The second capacitor (C.sub.2) is coupled between the output terminal (O) and the reference terminal (RF). The voltage converter disclosed herein can operate as an up converter, a down converter as well as a buffer.
