Abstract
Systems and methods are provided for dynamically biasing power amplifiers. In particular, dynamic biasing of a power amplifier may be controlled, with the controlling comprising receiving an input signal that is to be amplified; processing the input signal; generating based on said processing of the input signal input signal, a plurality of control signals comprising at least one biasing control signal; and applying the plurality of control signals to one or more control elements that are used in driving and/or control of the power amplifier. The one or more control elements may comprise at least one biasing component that adjusts biasing applied to power amplifier.
