By treating the resistor as an electromagnetic structure rather than a lumped element, and by managing coupling, shielding, thermal paths, and compensation as part of a unified design, it becomes possible to achieve ultra‑low insertion inductance and gigahertz‑class measurement bandwidth in a device small enough for production use. The result is a measurement element that enhances system performance rather than limiting it. As power systems continue to push toward higher speed, higher density, and higher reliability, the current‑sense resistor must evolve accordingly. In this article, Steve Sandler outlines a path to that evolution.

The 800G-ZR+ optics mark the next leap forward in network technology: double the data performance, higher efficiency, and lower energy consumption.

In this article, Tyler Huddleston explores causality in relation to signal and power integrity simulations. He reviews how causality affects time-domain simulation fidelity as well as how non-causal s-parameters can result from real measurements and simulations. Learn about how non-causal data can be avoided and the consequences of using a non-causal model in time-domain simulations.

This paper, awarded the Best Paper Award at DesignCon 2024, explores what is meant by bandwidth during the standardization process, the implications of test and verification attached to certain bandwidth requirements, as well as differences between acquisition range, band limited filters, and s-parameters for time domain processing. 

As PCIe technology continues to evolve to meet high bandwidth demands, the PCIe 7.0 architecture will focus on channel parameters and reach while improving power efficiency.

To provide designers with a reliable and robust network solution with deterministic communication, Microchip Technology today announces its next-generation of LAN969x Ethernet switches with time sensitive networking, scalable bandwidths from 46 Gbps to 102 Gbps, and a powerful 1 GHz single-core Arm Cortex-A53 CPU.

Demonstration achieves the first 310 GBaud rates using on-off keying modulation and 160 GBaud rates using PAM6 modulation with direct detection systems.

Rob Russell, VP of Satellite Business Unit at Vicor, discusses the challenges for power in the LEO and MEO satellite market and how those issues are being addressed with new architectures.

While we get the scope’s bandwidth from the vendor, as soon as we add a cable, probe, or amplifier to the scope, we decrease the system bandwidth. The new system bandwidth is as important to know as the scope’s bandwidth, but it is generally difficult to measure except in a calibration lab. We offer a simple method of evaluating the transfer function and system bandwidth of any probing system using a wide band noise source. This method not only gives us information about the probes and interconnects, but it also tells us how the scope responds to the measurement system, information which cannot be measured by a VNA alone.

Eric Bogatin explains the figures of merit in the time and frequency domain, and he steps through how to get a rough measure of the highest frequency components in a signal.
