Joon-Hoon Park, Byeong-Ju Kim · 2010
What with large volume and high power consumption, conventional audio amplifier is not suitable for resent mobile IT devices such as PMP, MP3 and notebook PC but a class-D amplifier is more appropriate for such mobile IT devices because a class-D amplifier has various advantages in digital and compact circuit design. In addition, by applying Li-polymer secondary battery and Bluetooth technology to a class-D amplifier, the system can be more portable and light. In this paper, a design and implementation method for wireless class-D stereo amplifier system is presented.
