We care about maintaining the same differential impedance for the same reason we care about maintaining the same instantaneous impedance of a single-ended (SE) transmission line: to avoid reflections. SIJ’s EAB member Bert Simonovich explains the fundamentals and why it matters.

Bert Simonovich explains why you should take your shot at becoming an industry influencer, offering tips to get started and to keep moving.

Check out this description of what is likely the fastest GaN edge-speed ever recorded.

Copper loss is one ingredient in interconnect loss. Surface texture or roughness has long been recognized as adding an excess loss over smooth copper. With the SI-VSP (very smooth profile) copper foils recently introduced by Mitsui Mining&Smelting Co. Ltd. (Mitsui Kinzoku), we may have reached the limits.

Watch out for those operating frequencies. Here are some tips to avoid EMC emission test failures.

Here’s what you need to do to enter to win copies of 9 books to round out your SI/PI library—one is out of print and one is hot off the press.

Here are some tips to prepare for a standards audit and avoid being assessed a deficiency.

Over the years, I have presented to and worked with thousands of engineers, from very young to very old. Many of the problems they bring to me have a small set of common answers. I’ve collected these into 20 basic rules of engineering.
