摘要
在PCB设计中,尤其是在高频电路中,经常会遇到由于地线干扰而引起的一些不规律、不正常的现象。本文对地线产生干扰的原因进行分析,详细介绍了地线产生干扰的三种类型,并根据实际应用中的经验提出了解决措施。这些抗干扰方法在实际应用中取得了良好的效果,使一些系统在现场成功运行。
In PCB design,especially in the high frequency circuit,often encountered a number of irregular,abnormal phenomenon, due to interference caused by the grounding. This article has analysised the reason of the grounding wire interference,describes three types of the grounding wire interferences,and proposed the solution measure according to the experience of the practical application. These technologies have practically brought about good effect, making some systems run successfully in the working places.
