摘要

本文分析了D类音频放大器中寄生和反向恢复对谐波失真的影响。将研究的误差源经验建模为振幅误差，然后采用基于牛顿数值方法的现有策略来模拟其在可听波段内的影响。将结果与现有的定时误差进行比较，以确定其支配程度。

Empirical analysis of the effect of parasitics and of reverse recovery as an amplitude error on distortion in a class D audio amplifier

An analysis of the effect of parasitics and reverse recovery on harmonic distortion in a class D audio amplifier is performed in this paper. The error sources under investigation are modelled empirically as an amplitude error, after which an existing strategy based on Newton's numerical method is implemented to simulate its effect within the audible band. The results are compared to existing timing errors to determine its degree of dominance.
