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.
This article presents methods for building reduced-order models (ROMs) based on proper orthogonal decomposition (POD) for modeling transient heat transfer in partially-perfuse tissue in prolonged contact with a heat-generating wearable device.
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.
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.
This article offers some useful insights and guidelines on how to effectively design and test systems using wide band gap devices to optimize product performance and achieve EMC compliance.
This paper provides a comprehensive study on how to mitigate desense with the change in the spectrum distribution by tuning the duty cycle of the interfering clock. Measurements conducted on a real cellphone showed a 10 dB suppression of desense for certain TX bandwidth condition.
The trend of progressively migrating both ESD and EMC immunity from the system/board to the component level is creating unprecedented challenges for the component ESD designer. Implications of EMC-ESD immunity co-design will be reviewed along with several case studies.
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.
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.
For engineers new to the field of EMC, the road can look very steep indeed. But, with a plan (and some work!), you can grow from EMC novice to EMC expert.
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.
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.
While the selection of components in electrical equipment plays a crucial role, a sound understanding of the characteristics of safety-critical and high-integrity components can provide valuable information about the ways to advance and achieve safety goals.
Product regulatory compliance is a formal discipline that addresses every aspect of the product lifecycle, helping to ensure global acceptance of new and innovative technologies that are environmentally sound and safe to use.
