In some instances, special, yet highly inefficient fixes are implemented to correct these design issues. These so-called “band-aid strategies” can include noise filters or adding decoupling capacitors ...

Editor's note: This article addresses the need for designers of printed circuit boards for nextgen ICs to be savvy about package-on-package technology. New ways of working with sub-assembly printed ...

Decoupling capacitors have long been an important aspect of maintaining a clean power source for integrated circuits, but with noise caused by rising clock frequencies, multiple power domains, and ...

This article discusses the impact of power integrity (PI) and power distribution network (PDN) impedance on simultaneous switching noise (SSN). The study is performed with post-layout PI simulation ...

Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct? These are the ...
