Claim:
1. Power supply for an electronic circuit, which power supply comprises: an input current source which generates a DC current for supplying power to an electronic circuit, a plurality of switched capacitor networks, each of which has a capacitor, a first set of terminals and a second set of terminals, and means for producing a switching signal connected to the switched capacitor networks, wherein the switched capacitor networks have a first mode of operation in which the input current source is connected by a first line to the first set of terminals and wherein a defined input voltage is generated by a voltage drop by the input current, the defined input voltage being connected to the second set of terminals through a transistor and a second line so that the plurality of switched capacitor networks are charged coupled in parallel, where the switched capacitor network has a second mode of operation in which the capacitors are switched by the switching signal from being coupled in parallel to being coupled in series for multiplying the input voltage to second higher output voltage which is supplied to a oscillating circuit via a transformer and half bridge driver, and wherein the supplied output voltage generates the input current from the input current source.
