1. A system for compensating a power amplifier for variations due to temperature comprising:

  • a power amplifier adapted to amplify an input signal based on a supply voltage, thereby producing an output signal; and

    circuitry adapted to generate the supply voltage based on a control signal and temperature such that a change in temperature results in a change in the supply voltage, wherein the change in the supply voltage offsets variations in characteristics of the power amplifier due to variations in temperature.
