An integrated class D audio amplifier based on sliding mode control

Year: 2008

Type: conference-paper

Abstract: Class D amplifiers are becoming the most feasible solution for embedded audio application. However, distortions due to the non-linear nature of switching stage are the main drawback for this amplifier topology. This paper discusses the design and implementation of high fidelity audio class D using sliding mode control scheme. This design method proves to be a cost effective solution for industrial circuit. Experimental IC results, using commercial 0.13 mum CMOS technology, verified the theoretical results: the efficiency is above 90%, THD is lower than 0.01% and PSRR is superior to 70 dB.
