Abstract: Class D audio amplifier can extend battery life for its small cubage and high efficiency. In connection with the advantages of Class D audio amplifier, a class D audio amplifier with high efficiency and low distortion is designed in this paper. A negative feedback is established to improve the linearity of the amplifier and power supply ripple rejection ratio. Minimizing the distortion of the system requires high-speed sampling. High-speed comparator is designed to meet this requirement. Moreover, the work req…
