Abstract: According to various embodiment, an electronic device may include at least one communication processor, an RFIC, a power amplifier, and at least one modulator configured to provide the power amplifier with a supply voltage set for a first unit of time in a first mode or in a second unit of time shorter than the first unit of time in a second mode. The at least one communication processor may be configured to control the at least one modulator to provide the supply voltage according to the second mode and to switch from the second mode to the first mode when a variation in a voltage associated with a first element for providing the supply voltage is greater than or equal to a threshold magnitude while the supply voltage is provided to the power amplifier according to the second mode. Other various embodiments are possible as well.
