This blog explains CDM ESD testing using the field-induced (FI) method, which is important for semiconductor manufacturers. It covers building a CDM-FI tester, waveform details and verification, and qualification nuances. 

This month's blog explains X-type capacitors, which suppress emissions in switch-mode power supplies and variable drives.

As a product designer, a major issue you'll face is radiated emissions. This month, we'll outline the basic tools to characterize and mitigate radiated emissions at your workbench. This summarizes the fundamental test equipment to identify sources of harmonic noise and characterize radiated emissions.

This column describes the operation of an ideal difference amplifier. It is shown that an ideal difference amplifier (with no resistance mismatches) eliminates the common mode portion of the input voltage and amplifies only the differential mode portion of the input voltage.

The behavior of ultra-high-speed interfaces is complex, involving fast-rise time waveforms and on-die transient phenomena that cause device failure at lower CDM levels.

Solving EMI problems isn’t only about ensuring that a product can meet EMC regulations and standards (although it’s a significant part of the job). Another crucial reason for addressing EMI issues is to enhance product reliability, especially when a product operates in public or industrial areas where there are many different types of noise sources.

A manufacturer of electrical test equipment took an order worth several million dollars for new product to be used worldwide to help service the vehicles manufactured by a major multinational.

To avoid costly errors in selection, invest the time upfront to gain a basic yet thorough grasp of key amplifier specifications and operating principles before identifying the optimal model for your application needs.

Making time for even just 30 minutes of focused reading each day will keep you on the path of continuous learning.

What if you could confidently characterize and resolve EMC vulnerabilities before they escalate to profit decimation?
