Abstract
The representative embodiments discussed in the present disclosure relate to techniques in which the operating characteristics (e.g., power consumption) of a power amplifier in a transceiver may be regulated according to an operation mode of the transceiver. More specifically, in some embodiments, different LUTs may be employed for each mode of operation to suitably adjust the supply voltage (e.g., bias voltage) and/or quiescent current input to the power amplifier based on an input signal and a margin by which transmission standards are met. Further, in some embodiments, a method to calibrate a LUT for average power tracking and/or envelope tracking in a transceiver mode of operation may be employed to populate a LUT that may be used to suitably adjust the power and/or current consumption of the power amplifier.
