Ultra-Low Insertion Inductance, Ultra-High-Bandwidth Resistors

Tue, 21 Apr 2026 00:00:00 -0400

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.

Mitigating Ground Loop Errors in High-Current PDN Measurements: Validating Measurement Accuracy Across Oscilloscope Platforms

Mon, 16 Mar 2026 01:00:00 -0400

As currents increase and voltage rails shrink, managing fluctuations becomes a critical challenge. While probe noise is a major factor, the common-mode noise induced by the ground loop between the high-current DUT and the oscilloscope is often the more dominant disruptor in high-current AI environments. This experiment proves that simply switching oscilloscope vendors will not solve the problem. Read on to learn why the solution lies in the probing chain.
