摘要： A switching amplifier is provided. The switching amplifier includes an input unit which receives an audio signal; a first switching device and a second switching device which switch and output the audio signal; a first snubber circuit which is commonly connected to the first and second switching devices and which reduces overshoot of the audio signal that is output by the first and second switching devices via switching; and a second snubber circuit which is commonly connected to the first and second switching devices, which is connected in parallel to the first snubber circuit and which reduces the overshoot of the audio signal, wherein the first and second snubber circuits alternately reduce the overshoot of the audio signal.

摘要： A method of outputting an audio signal includes receiving an audio signal; generating a carrier waves having phases differing from each other; generating modulation signals by comparing the respective carrier waves with the audio signal; amplifying the modulation signals; and outputting the amplified modulation signals.
