Patent ID: 8478213

Claim:
A method for controlling power in a transmitter, the method comprising: measuring an indication of an output power of the transmitter; comparing a first value corresponding to the indication of the output power to a second value corresponding to a desired output power in order to create and error signal; based on the error signal, setting a power supply voltage to be applied to a power amplifier of the transmitter, the power amplifier including an output coupled to an antenna of the transmitter, wherein the power supply voltage is set as a voltage level to produce the desired output power from the transmitter, and based on the error signal, and after setting the power supply voltage of the power amplifier, adjusting a bias of at least one of a digital-to-analog converter, a mixer, and a pre-power amplifier, wherein the digital-to-analog converter, the mixer, and the pre-power amplifier are coupled to the power amplifier, and wherein adjusting the bias of at least one of the digital-to-analog converter, the mixer, and a pre-power amplifier includes adjusting the bias in order to achieve the desired output power for the transmitter.
