Abstract
A signal generation power management control system () for use in a portable communications device includes a digital signal processor (DSP) () for processing a digital source input and providing a digital processed bit stream A digital-to-analog converter (DAC) () is used for converting the digital processed bit stream to provide an analog signal. A power management controller () within the DSP () is then used for interpreting control parameters of signal processing components used within the portable communications device and dynamically adjusting the bias current of these components based on minimal signal requirements of the analog signal.
