摘要：

Large-signal performance of digital audio amplifiers is a critical parameter. Methods are described that improve the large-signal performance of a digital PWM modulator and feedback loop significantly. The resulting system is capable of maintaining excellent performance as the signal amplitude approaches the theoretical maximum duty ratio of 100%. The large-signal performance of a high-power digital PWM audio amplifier utilizing these methods is characterized in detail.
