Optimization Methods for Amplifier with Variable Supply Power

摘要

Optimization methods via various circuital arrangements for amplifier with variable supply power are presented. In one embodiment, a switch can be controlled to include or exclude a feedback network in a feedback path to the amplifier to adjust a response of the amplifier dependent on a region of operation of the amplifier arrangement (e.g. linear region or compression region).

1. A circuit comprising:
an amplifying arrangement configured to operate in a compression region of the amplifying arrangement and/or in a linear region of the amplifying arrangement; a variable power supply operatively coupled to the amplifying arrangement and adapted to provide a dynamic supply power to the amplifying arrangement; and an optimizing circuital arrangement operatively coupled to the amplifying arrangement and configured to operatively affect a response of the amplifying arrangement depending on the region of operation of the amplifying arrangement thus impressing a desired effect upon a radio frequency (RF) output of the amplifying arrangement.
