Abstract
A supply modulator includes a linear regulator that generates an output voltage in an envelope tracking mode. A switching regulator operates with the linear regulator to generate the output voltage in the envelope tracking mode and to selectively generate the output voltage in an average power tracking mode. A single inductor multiple output converter operates selectively with the switching regulator to generate the output voltage in the average power tracking mode, operates to provide a power supply voltage to the linear regulator in the envelope tracking mode, and includes a first capacitor connected with a power supply terminal of the linear regulator and a second capacitor selectively connected with an output terminal of the linear regulator through a first switch. A main controller decides a tracking mode to be executed by the supply modulator.
