发明名称 Power control techniques for wireless transmitters
摘要 Various embodiments are disclosed relating to power control techniques for wireless transmitters. In an example embodiment, an apparatus is provided that may include a digital-to-analog converter (DAC) adapted to convert a digital amplitude signal to an analog amplitude signal during a first transmission mode and adapted to convert a digital power level signal to an analog power level signal during a second transmission mode.

主权项 1. An apparatus comprising: a digital-to-analog converter (DAC) adapted to convert a digital amplitude signal to an analog amplitude signal during a first transmission mode and adapted to convert a digital power level signal to an analog power level signal during a second transmission mode; and a switch coupled to an output of the DAC and configured to be operable to couple the analog amplitude signal output of the DAC through a sampling circuit to a power control circuit during a first transmission mode, and to couple the analog power level signal to a driver circuit during a second transmission mode; wherein one of the transmission modes includes a transmission mode that employs at least amplitude modulation, and wherein another one of the transmission modes includes a transmission mode that employs at least phase modulation or frequency modulation.
