电路系统接地技术研究

Study of Grounding Technologies of Circuit System

在电路设计中,接地的重要性众所周知,电子产品的很多问题都与接地的处理密切相关。本文通过对几种典型的接地方法,如PCB接地设计、多板卡系统接地设计、混合信号系统接地设计及取样时钟电路接地设计等进行分析,尽量避免在电路系统的设计过程中因为接地而出现的各种问题。

The importance of grounding technology is well-known in circuit design. A large number of problems with electronic products are closely related to grounding issues. Some typical grounding technologies, such as the PCB grounding technology, the grounding technology of multi-board system, the grounding technology of mixed signal system and the grounding technology of sampling clock circuit, are analyzed so that many problems with grounding technology can be avoided in circuit design.
