Characterizing and Mitigating Self-Generated EMI in Wireless & IoT Devices

Share

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.
