Parallel correction amplifier

摘要

A power supply stage and a method of controlling the same 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.

1. A power supply stage comprising:
a stage configured to generate 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 respective corrected signal tracking the reference signal, and wherein the corrected signal is based on a feedback signal; at least a first combiner adapted to combine each of the respective corrected with the intermediate supply signal to generate a plurality of adjusted signals, wherein each of the adjusted signals provides power to a respective power amplifier; and at least a second combiner adapted to combine the plurality of adjusted signals to generate the feedback signal.
