Abstract
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.
