Abstract: A power supply circuit includes a switched-capacitor circuit configured to generate, based on an input voltage, a plurality of discrete voltages; a first supply modulator configured to select, based on a first envelope signal of a first radio frequency signal, at least a first discrete voltage from the plurality of discrete voltages to output to a first power amplifier; and a second supply modulator configured to select, based on a second envelope signal of a second radio frequency signal, at least a second discrete voltage from the plurality of discrete voltages to output to a second power amplifier. The first power amplifier is configured to amplify the first radio frequency signal. The second power amplifier is configured to amplify the second radio frequency signal. The first radio frequency signal is a cellular network signal. The second radio frequency signal is a wireless local area network signal.
