This series of articles delves into the design principles of power filters for switched-mode power converters and similar applications, focusing on conducted and radiated emissions. Part 1 provides an overview of filter design principles, emphasizing the need for specialized approaches to meet EMC specifications in an increasingly electrified and sustainable world.

As part of a broader effort to expand health outcomes across diverse populations in the U.S., the U.S. Food and Drug Administration (FDA) has published a Discussion Paper to facilitate a public discussion on how to advance health equity in connection with medical devices.

The U.S. Federal Communications Commission is seeking comment on a wide range of changes to its rules applicable to frequency bands used by the Citizens Broadband Radio Service.

This article discusses the risks of electrostatic discharge (ESD) in healthcare settings and the new ESDA TR29 guidance document. It outlines causes of ESD, potential hazards like equipment malfunction and data loss, and preventive measures such as static control flooring, proper grounding, and humidity control. The article also describes recommended ESD control programs for healthcare facilities.

This paper provides a quick overview of aerospace engine testing solutions for engine vibration/balancing as well as signal conditioning technology from MTI instruments.

On a bright note, a teacher at a high school in Staten Island, NY is helping to train the next generation of America’s amateur radio operators!

The Enforcement Bureau of the FCC has reached a settlement with a telecommunications provider in connection with charges that the company transmitted illegal, AI-generated robocalls.

As expected, the U.S. Federal Communications Commission has published a formal version of its rules to address the growing use of AI in generating robocalls.

The U.S. Federal Communications Commission has released a new version of its smart device application that enables users to evaluate the speed of their mobile broadband connection.

A Charged Device Model (CDM) simulation method has been demonstrated to predict CDM fail current of receiving circuits with gate oxide connected to pad. This method involves inclusion of 20ps rise time edge into the stimulus. It was shown previously that this fast rise time component of the pulse can cause the gate oxide damage. The simulation method is intended as a schematic-level tool during pre-silicon design phase to deliver CDM ESD protection. Simulation results are verified by silicon results with qualification CDM test on package and Transmission-Line-Pulse (TLP) measurements on wafer-level.

This study examines the impact of complex magnetic permeability in 3-D simulations of toroidal ferrites and magnetic cores for EMC applications, revealing its importance and limitations at different frequencies.

This article provides an overview of high-altitude electromagnetic pulses and the damaging effects they pose to sensitive electronic circuitry, equipment and systems that support a wide range of critical applications, along with common EMP protection approaches and current testing methods used to evaluate the resilience of equipment and systems exposed to an EMP attack.
