Abstract
An exemplary embodiment discloses a digital control block for dynamically regulating power consumption of the transmitter; and a first driver amplifier circuit comprising a plurality of bias-modes each corresponding to a power consumption level in the transmitter, the digital control block to instruct the first driver amplifier circuit to operate in a selected bias-mode to regulate power consumption of the transmitter.
Claims30
A radio-frequency (RF) transmitter comprising:
- a digital control block for dynamically regulating power consumption of the transmitter;
- and
- a first driver amplifier circuit configured to receive at least one digital control instruction from the digital control block and comprising a plurality of bias-modes each corresponding to a power consumption level in the transmitter, the digital control block to instruct the first driver amplifier circuit via the at least one digital control instruction to operate in a selected bias-mode based on a measured output power level of the transmitter to regulate power consumption of the transmitter.
A method comprising:
- dynamically regulating a power consumption of a radio-frequency (RF) transmitter, via digital control instructions received at a first driver amplifier and based on a measured output power level of the transmitter;
- and
- selecting based on the digital control instructions a bias-mode of the first driver amplifier circuit comprising a plurality of bias-modes corresponding to power consumption levels in the transmitter.
An apparatus comprising:
- means for dynamically regulating a power consumption of a radio-frequency (RF) transmitter, via digital control instructions received at a first driver amplifier and based on a measured output power level of the transmitter;
- means for selecting based on the digital control instructions a bias-mode of the first driver amplifier circuit comprising a plurality of bias-modes corresponding to power consumption levels in the transmitter;
- and
- means for operating the first driver amplifier circuit in the selected bias-mode.
