Claim 13:
14. The method of claim 10, wherein the monitoring the digital amplitude signal, the identifying the present compensation value, the generating the compensation signal, and the outputting the compensation signal are performed during an operating phase, and the method further comprises, during a calibration phase prior to the operating phase:
generating the respective compensation value for each gain setting of at least a portion of the plurality of gain settings by:
setting the digital amplitude signal to indicate the gain setting, such that the power amplifier circuit generates the signal output according to the gain setting;
detecting a present output valley level of an amplitude envelope of the signal output at the gain setting;
computing a respective one of the plurality of compensation values based on the detecting the present output valley level for the gain setting; and
storing the respective one of the plurality of compensation values in the lookup table in association with the gain setting.
