Difference Amplifier: Common Mode and Differential Mode Voltages

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.

Challenges of CDM Modeling for High-Speed Interface Devices

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.

Using a Near-Field Probe to Troubleshoot Transient Failures

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.
