A power clipping circuit and method of the clipping circuit is provided. A power clipping circuit comprises, a selector which receives a baseband signal, and selects one of the baseband signal or a feed back signal, and outputs a selected signal, and a square clipping circuit which receives the selected signal, and limits an amplitude of the selected signal, and outputs a clipped signal, and a phase rotation circuit which receives the clipped signal, and rotates a phase of the clipped signal, and outputs a phase rotated signal to the selector as the feed back signal, and an amplitude scaling circuit which receives the phase rotated signal, and adjust the phase rotated signal to compensate an amplitude difference between the phase rotated signal and the clipped signal, and sends amplitude scaled signal, and a controlling circuit which controls the selector, the square clipping circuit, the phase rotation circuit and the amplitude scaling circuit.
