April 27, 2021: " Characterizing and Mitigating Self-Generated EMI in Wireless & IoT Devices " Kenneth Wyatt, Wyatt Technical Services
Presentation Video
Abstract:
It is fairly common to find multiple on-board sources of energy causing EMI on today's portable, mobile, and IoT devices. This usually includes digital bus noise, clocks and especially DC-DC converters. The EMI from these energy sources can couple and often interferes with the receiver performance of cellular, GPS and other wireless modules. This presentation describes methods for identifying, characterizing and reducing the coupling from these energy sources. We’ll wrap up with ten tips for reducing DC-DC converter coupling and EMI and a case study.
Bio: Kenneth Wyatt is principal consultant of Wyatt Technical Services LLC and served three years as the senior technical editor for Interference Technology Magazine from 2016 through 2018. He has worked in the field of EMC engineering for over 30 years with a specialty is EMI troubleshooting and pre-compliance testing. He is a coauthor of the popular EMC Pocket Guide and RFI Radio Frequency Interference Pocket Guide. He also coauthored the book with Patrick André, EMI Troubleshooting Cookbook for Product Designers, with foreword by Henry Ott. He recently published Creating Your Own EMC Troubleshooting Kit (Volume 1), which is the first in a series on troubleshooting and pre-compliance testing techniques that may be performed on the workbench in-house. The foreword for this was written by Martin Rowe, his long-time editor at EDN.com. He is widely published and authors The EMC Blog hosted by EDN.com and continues to blog for Interference Technology. Ken is a senior member of the IEEE and a longtime member of the EMC Society.
