At the 2015 IEEE International Symposium on Electromagnetic Compatibility and Signal Integrity held last month in Santa Clara, I attended two technical presentations related to PCB power planes. One, ...

A printed circuit board (PCB) is much like a complicated city, with a myriad of intertwined pathways for data signals and power. To meet the electric current needs of modern, high-powered integrated ...

The power distribution network (PDN) is a system that transfers low noise and stable power to the loads (e.g., ICs) on a PCB. It also provides a low impedance return path for signals’ current flow.

Also known as power distribution network. Getting power around a semiconductor device is complicated and expensive. It generally starts at a power supply and transferred by wires to a printed circuit ...

This paper discusses the importance of low PDN (power-distribution network) impedance on high-speed PCBs, and the ways to achieve lower impedance at high frequencies. The study is conducted with ...

We generally associate the Power Distribution Network (“PDN”) with the power circuits used to drive CPUs and FPGAs. The increasing use of FPGAs in our products certainly means that at some point we ...
