Abstract
Official abstract text for this publication.
There is disclosed a power supply stage, and a method of controlling such, comprising: a means for generating an intermediate supply signal in dependence on a reference signal representing a desired power supply; and a plurality of adjusting means, each adapted to generate an adjusted supply signal tracking the reference signal, in dependence on the generated intermediate supply signal and the reference signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A power supply stage comprising: a stage for generating an intermediate supply signal in dependence on a reference signal representing a desired power supply; a plurality of correction amplifiers, each adapted to generate a corrected signal based on an output power supply voltage of the power supply stage and wherein the corrected signal tracks the reference signal; and a combiner for combining the plurality of generated corrected signals and the interm…
