摘要

开关稳压器产生的噪声(VR噪声)会对系统信号/功率性能产生很大影响，导致信号完整性(SI) /功率完整性(PI)问题。本文介绍了降低虚拟现实噪声的系统方法以及虚拟现实噪声的分析方法。最后给出了一个具有虚拟现实噪声问题的实际设计案例，并给出了仿真和测量结果。

VR noise analysis and reduction in printed circuit board designs

Noise caused by switching voltage regulator (VR noise) can have a big impact on system signal / power performance, leading to signal integrity (SI) / power integrity (PI) issues. This paper introduces systematic ways of reducing VR noise as well as VR noise analysis methods. And a real design case with VR noise issue is shared with simulation and measurement results.
