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. |

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. |
