Abstract
Aspects of compensating for transmitter output power may comprise sampling an on-chip transmitter circuit temperature at various time instants and determining a feedback temperature compensation value. At least one digital-to-analog converter may be adjusted by utilizing the feedback temperature compensation value, which may correspond to the sampled temperature. The digital-to-analog converter may be an I-component digital-to-analog converter and/or a Q-component digital-to-analog converter. At least a portion of the on-chip transmitter circuit may be characterized to determine power output dependence of the on-chip transmitter circuit on temperature variation of the on-chip transmitter circuit. Based on this characterization, a feedback temperature compensation value that may correspond to the sampled temperature may be used to adjust the digital-to-analog converter. The feedback temperature compensation value may be, for example, from a lookup table or an algorithm.
