深入地研究了Sigrna—delta ADC的结构和工作原理,并详细地讨论了用根轨迹法对调制器稳定性进行验证的方法,最后给出了使用MATLAB的计算机仿真结果,仿真很好地证明了上述方法的有效性和可靠性。
In this paper, the structure and working principle of Sigma-delta ADC modulators are thoroughly studied. And the stability analysis using root-locus method is discussed in detail. Finally, the formulation resuits using MATLAB are given, which show the feasibility and credibility of this method.
