Abstract
According to prior art, a clock frequency increase for clocked high-frequency integrated circuits, in particular microprocessors, reaches a current physical limit of approximately 3 GHz, as dynamic current modifications cannot be sufficiently compensated. The aim of the invention is to provide a power supply for electronic systems with a double-figure GHz range. To permit the rapid compensation of dynamic current modifications, the current compensation circuit (10) is placed in the vicinity of the integrated circuit (11) or is integrated into the latter. A control amplifier (8) influences a pulsewidth modulator (2) by means of an optical coupler (9). Said pulsewidth modulator control controls a normal mode voltage converter (3, 4) with synchronous rectification (5). A specific application area for the invention is the supply of future high-performance microprocessors, whose development has been delayed by the aforementioned power problem.
