Abstract: The disclosure relates to a 5G or 6G communication system for supporting a data transmission rate higher than a 4G communication system such as LTE. An electronic device in a wireless communication system may include a PA and an SM configured to supply power to the PA, wherein the SM may include a linear SM to which a signal for an envelope tracking (ET) is input, and a first SM connected to the linear SM and comprising a first converter for direct current (DC)-DC conversion and at least one lumped element connected to the first converter, and the first SM may be configured to convert the signal for the ET into a first digital signal, to generate a first control signal for the first converter based on a change of a voltage value of the first digital signal, to generate a second digital signal by delaying the first digital signal by a predetermined clock, and to control the at least one lumped element based on the first digital signal and the second digital signal to adjust a current output from the first SM.
