1. An apparatus for dynamic adjustment of a power amplifier bias of a power amplifier, comprising:
circuitry, disposed within the apparatus, performing a measurement of a power level presently being handled by the power amplifier;
the circuitry adjusting the power amplifier bias for a power amplifier based on the measurement of the power level presently being handled by the power amplifier and a desired fidelity experienced by RF signals processed by the power amplifier, wherein the threshold for raising the power amplifier bias is capable of being satisfied in less time than the threshold for lowering the power amplifier bias.
