Ever wonder how much energy is required to transmit data and why so much power is dissipated into heat? SIJ EAB member Yuriy Shlepnev takes a closer look.

Who doesn’t love an easy-to-use 2D field solver to calculate the single-ended or differential impedance of PCB transmission lines? Eric Bogatin takes this one from Sierra Circuits for a test drive.

The higher speed of USB4 has prompted a move to retimers and away from redrivers within USB-C systems. This article describes the method of designing retimers into USB4 systems.

In this Extreme Measurement story, the goal was to determine the dynamic current of the FPGA by measuring the AC current in an external VRM using a transformation of the PCB S-parameters and the simultaneous measurement of the AC voltages across the PDN.

In this inaugural post in his new Practical EMC blog on Signal Integrity Journal, Kenneth Wyatt lays out the major tools to troubleshoot and test for EMC compliance.

Check out this latest installment in the Extreme Measurements Blog that covers the measurement challenges for GaN switches.

It may have gone somewhat unnoticed but for the first time ever, Ansys released software into the open source late last year. The software is PyAnsys, a family of Python packages providing a new, unified programmable interface to the company’s proprietary simulation stack. Learn more about this development.

I do not know if there was a legitimate reason for this request, but I was once asked to determine the turns ratio of a power transformer inside a sealed, DC-DC converter module.  In any case, there is not much usable information since the module is sealed, but we can apply a simple trick. Check out this latest installment in Extreme Measurements.

Impedance is the most fundamental and important electrical property of any component. With a very simple technique, anyone can simulate the impedance of any circuit in seconds using any version of SPICE, for free. Read on to learn more.
