Figure 1 depicts two 100Ω differential pairs of PCB (printed-circuit-board) traces. A solid-plane layer appears at the bottom of the figure. An upper solid plane exists somewhere above the figure.

I wrote about my IC designer buddy Don Sauer in this post. He has developed a spreadsheet to help design dual differential-pair front ends. He sent the spreadsheet to Charles Williams, the guy that ...

PCIe, also known as PCI-Express, is a highly powerful interface. So let’s see what it takes to hack on something that powerful. PCIe is be a bit intimidating at first, however it is reasonably simple ...
