Abstract
A power amplifier with a low distortion and a high power efficiency includes a first amplifier of the low distortion type for being powered by a first voltage source to amplify an input signal thereto to apply an output signal to a first terminal, and a second amplifier of the high power efficiency type for being powered by a second voltage source to amplify the input signal to apply an output signal to a second terminal. A load is connected between the first and second terminals. The output voltage of the second voltage source is greater than that of the first voltage source. A first feedback path is provided for feeding back the output signal of the first amplifier to an input thereof. A second feedback path is provided for feeding back the output signal of the second amplifier to the input of the first amplifier.
