Abstract
A method and a supply modulator (SM) are provided for supplying power from a wireless transmitter to a radio frequency (RF) power amplifier. A power control signal input from a modem is received. A reference voltage is determined. An operating mode of the SM is changed by controlling a level of the reference voltage. A voltage is determined based on the level of a reference voltage. When the operating mode of the SM is an ET mode, a first output signal from a linear regulator and a second output signal from a switching regulator are combined to obtain a combined result, and the combined result is output. The first output signal is based on the voltage. When the operating mode of the SM is an APT mode, the voltage based on the reference voltage is output.
