Low-Frequency Magnetic Field Shielding

Occasionally, we are asked to help develop shielding effective for near-field low-frequency (LF) magnetic fields, perhaps in a situation where some regulatory agency has imposed limits on LF magnetic field emissions of our product, and we are forced to comply.

The Duty to Warn

Even though warnings and instructions are not followed by all product users, they are important for product safety and product liability defensibility. Manufacturers must decide how safe to design their products and when they can also rely on warnings and instructions to make the product safe.

ESD Co-Design for High-Speed SerDes in FinFET Technologies

The narrow ESD design window in current FinFET technologies creates a special challenge for the robust ESD design of high-speed interfaces. Smart circuit-ESD co-design can help achieve the required ESD robustness without deteriorating functional performance.

NASA Space Shuttle’s Return to Flight: The Untold Electromagnetic Backstory

The 2003 Columbia re-entry accident was caused by a piece of liberated external tank foam that struck and damaged the left leading edge during powered ascent. Computational and experimental electromagnetics were ultimately applied to foster the development of a new NASA Ascent Debris Radar (NDR) for the remaining 22 Shuttle missions. In the process, countless static and dynamic radar signature and EMI/EMC calculations and tests were completed to assure this safety-critical radar system was ready for the return to flight (RTF) missions.

Continuing Your Professional Education in 2022

Traditionally, the start of a new year is a time when we reflect on the progress we’ve made during the year passed and set our goals for the new year. We’ve queried training resources in our industry to provide you with an overview of free or affordable solutions to meet your training goals in 2022.

Capacitors: Theory and Application

This article presents the fundamentals and application of capacitors. What is a capacitor, and how do we select them? Techniques of selecting capacitors and things to consider when using capacitors are highlighted. Both practical examples and simulation are used to demonstrate the key points.

Ohm’s Law Also Applies to ESD‑Induced Heat Pulses

Heat flow analysis for semiconductor ESD situations can be approximated to one dimension, and then captured with a generalized Ohm’s Law using a complex impedance. Methods can include time-dependent electrothermal pulses and feedback due to self-heating, with solutions readily carried out on any desktop computer.
