The reduction of switching VR impact on PCB signals
Microsystems, Packaging, Assembly and Circuits Technology Conference(2014)
Abstract
Noise caused by switching voltage regulator (VR noise) can have big impact on system performance, causing signal integrity (SI) / power integrity (PI) issues. This paper introduces systematic ways of reducing VR noise at source, in coupling path and at receiver. Examples are also shared.
