Abstract
An apparatus and a method for raising an output efficiency in a mobile communication terminal are provided. The apparatus includes a supply modulator and a power amplifier. The supply modulator includes a DC-DC converter, a voltage regulator, and a switching regulator. The supply modulator modulates an envelope component of an input signal to generate power. The power amplifier amplifies a phase component of the input signal using the power generated by the supply modulator as a power source of a collector/drain. The DC-DC converter raises battery power of the mobile communication terminal. The voltage regulator determines an output voltage of the supply modulator using the power raised by the DC-DC converter. The switching regulator determines an output current of the supply regulator using the battery power of the mobile communication terminal.
