Abstract:
1. A wireless transceiver having a receiver core coupled to a power amplifier, comprising: power detection circuitry coupled to an output of the power amplifier for providing a detected power level and a reference power level; 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 a power control signal corresponding to a difference between a variable power level signal and the feedback power signal, a transmit core of the wireless transceiver adjusting an output gain in response to the power control signal.
