Abstract

In embodiments, an electronic device is provided. The electronic device includes a processor including processing circuitry, a radio frequency (RF) transceiver, a first power supply circuitry for providing a power amplifier with a first supply voltage, a second power supply circuitry for providing the power amplifier or another power amplifier with a second supply voltage, a first power path connected to the first power supply circuitry, a second power path connected to the second power supply circuitry, wherein a third supply voltage is provided through the third power path, a first switching circuitry configured to connect or not connect the third power path to the first power path, a second switching circuitry configured to connect or not connect the third power path to the second power path, and a radio frequency front end (RFFE) module, including the power amplifier, connected to the first power path and the second power path. The first switching circuitry is controlled to connect the first power path and the third power path while the first supply voltage is not provided to the power amplifier through the first power path. The second switching circuitry is controlled to connect the second power path and the third power path while the second supply voltage is not provided to the power amplifier through the second power path.
