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 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.

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 article explains how to use a Smith Chart to determine the voltage standing wave ratio (VSWR).

Standards continuously evolve, and EOS/ESD Association, Inc. standards are no different. The ESDA is always striving to achieve the highest quality standards.
