摘要
在分析噪声的基础上,对公共阻抗耦合的噪声及其产生、危害进行了较全面的介绍,讨论分析了接地技术即一点接地法、多点接地法在抑制该噪声中的应用,并总结出了它们的使用条件,为优化设计低噪声电路提供了有力的工具。
On the basis of noise analyzing, this paper fully expounds the noise produced by common impedance coupling, the influence on the electronic circuits; grounding technology and the application fields of different earthing methods are discussed here. Effective formula is provided to facilitate the low-noise design of the circuit.
