摘要： An adaptive power amplifier that may be used in a wireless communication device is configured to adjust its load line or output impedance, the number of active amplifier cells in each amplification stage, the bias of the active amplifiers, and the supply voltage input capacitive load in accordance with a supply voltage modulation type provided to the power amplifier. The supply voltage modulation types include ET, APT, DC-DC, dual, multi-state or fixed voltage supply voltages. A supply voltage converter, signaled by a baseband processor, generates the selected type of supply voltage modulation for the adaptive power amplifier. The baseband processor may also provide a control interface signal to a controller within the adaptive power amplifier. The controller, based on the received control interface signal provides a configuration signal that configures the impedance, the number of active amplifier cells, the bias of the active amplifier cells, and the supply voltage capacitive load to optimize the adaptive power amplifier based on the supply voltage modulation type.

摘要： A method is performed on an integrated circuit, for generating a composite envelope reference voltage for a plurality of transmit signals. The method includes, generating a composite baseband signal from a plurality of baseband signals, wherein the plurality of baseband signals represent a corresponding plurality of different transmit signals (402). The method also includes calculating a composite envelope signal for the composite baseband signal (404), and generating a composite envelope reference voltage from the composite envelope signal for use in powering a single power amplifier as the power amplifier transmits the plurality of different transmit signals (406).
