发明名称 Envelope modulator saturation detection using a DC-DC converter
摘要 In an embodiment of the invention, a system provides for efficient polar and linear signal modulation. The system has a controller coupled to a voltage converter and a modulator. The system also has an amplifier coupled to the voltage converter and the phase modulator. The controller is for receiving an input and providing a polar signal. The voltage converter is for receiving the polar signal, receiving a voltage input, and providing a power signal. The amplifier is for amplifying the modulated signal based on the power signal. The voltage converter provides a feedback signal to the controller, and the controller adjusts a scale of modulation, such as a peak of the modulation signal, based on the feedback signal, such that the output power and the amplification by the amplifier are based on the feedback signal.
