Eric Bogatin博士在信号完整性普及推广方面做出了极大的贡献,他对于信号完整性的深刻理解非常令人敬佩。本文附件是Eric博士2011年发表的一篇文章,特别强调了9个重要的基本原理,特别推荐给大家。内容讲述的极其简练,但每一条都触及根源,个人认为不论对于初学者还是老手都值得一看。信号完整性理论知识繁杂,为什么单单强调这些东西?仔细品味,相信你会有所收获。现将9条列出如下。 1. All Interconnects Are Transmission Lines 2. Signals Are Dynamic 3. Signals See an Instantaneous Impedance 4. The Return Current Is Just as Important as the Signal Current 5. Reflections Occur Whenever the Instantaneous Impedance Changes 6. Inductance Is Fundamentally About How Efficient a Conductor Is in Generating Rings of Magnetic Field Lines 7. Current in a Conductor Redistributes at Higher Frequency Driven by Minimizing Loop Inductance 8. Dielectric Materials Absorb Electric Field Energy and Cause Attenuation 9. Common Currents in Conductors Radiate and Often Cause EMC Failures
