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.

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 ...

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 ...

The ability to operate at up to 25A is made possible by a new, thermally enhanced 5 x 6 mm PQFN (Power Quad Flat No-Lead) package using a copper clip, as shown in Fig. 1. Fig. 1. Fabrication of the ...
