An electronic device, comprising;
- a processor, comprising processing circuitry;
- a radio frequency (RF) transceiver;
- a first radio frequency front end (RFFE) module including a first power amplifier;
- a second RFFE module including a second power amplifier;
- and
- a power supply module including a first power supply circuit for the first power amplifier, a second power supply circuit for the second power amplifier, a linear regulator, and a switching circuit configured to selectively connect an output of the linear regulator to the first power supply circuit or the second power supply circuit,
- wherein the switching circuit is controlled, in accordance with the processor or the RF transceiver, to:
- in a first state, provide, while providing a first supply voltage to the first power amplifier through the power supply module based on an envelope tracking (ET) mode using the linear regulator and the first power supply circuit, a second supply voltage to the second power amplifier through the power supply module based on an average power tracking (APT) mode using the second power supply circuit, and
- in a second state, provide, while providing the first supply voltage to the first power amplifier through the power supply module based on an APT mode using the first power supply circuit, the second supply voltage to the second power amplifier through the power supply module based on an ET mode using the linear regulator and the second power supply circuit.
A power supply module comprising:
