摘　　要：本文以AD73360为例,讨论了模数转换器在级联使用时容易遇到的共性问题.首先分析了在电路板设计时,对于功能相同性能又各自独立的电路功能模块在EDA布线时采用公共回路的地线噪音给系统稳定性带来的影响;随后讨论了级联模式下导致串行数据线误码问题的可能原因,并提出在EDA布线阶段对上述问题的解决方案及建议.This article analyzes the common problems existing in cascade model operation of analog to digital converter AD73360 and proposes potential solutions.A mathematical model is established based on kirchhoff’s law.Causes of performance issues such as drifting are rationalized by analyzing parameters varying per PCB layout.A special case of ADC faulty initialization is also addressed and recommendations are made to optimize the design application in EDA layout design.
