Closed-loop digital power control for a wireless transmitter

A wireless device comprising:

• a power amplifier coupled to an antenna;
• and,
• a wireless transceiver coupled to the power amplifier, the wireless transceiver including a transmit core for providing an output radio frequency signal having an output gain in response to a gain control signal, the output radio frequency signal being provided to the power amplifier, power detection circuitry coupled to an output of the power amplifier for providing a detected power level and a reference power level;
• a receiver core having analog to digital conversion circuitry for converting the detected power level into a digital power level and for converting the reference power level into a digital reference power level;
• a power signal processor for subtracting the digital reference power level from the digital power level, and for providing a feedback power signal corresponding to the difference between the digital power level and the digital reference power level, and a power correction circuit for providing the gain control signal corresponding to a difference between a variable power level signal and the feedback power signal.
