This article discusses the basics of a step-down (buck) DC Switched-Mode Power Supply (SMPS). It should serve at an entry-level tutorial and a building step towards the more advanced designs.

CDM discharges exhibit a fast initial current step when the stray capacitance of the pogo pin is charged. It is demonstrated that the high slew rate can damage sensitive gate oxides. The miscorrelation of CDM and CC-TLP methodologies is addressed by applying pulses with 20 ps rise time.

Cable discharge events occur more frequently than we think, but they often go unrecognized or undiagnosed for root causes, resulting in unnecessary device failures. This article discusses the origins of three types of cable discharge events.

Confusion over ESD flooring resistance terminology and requirements abounds, leaving many in the dark and creating potential risks. This article helps to clarify this complicated issue so that you can work to mitigate the problem.

This article is about varistor construction, characteristics, testing and the often-unappreciated ways varistors can fail.

Optical communication can dramatically increase the bandwidth between servers while reducing complexity, power consumption, and cost.

If you’re performing commercial radiated and conducted emissions measurements strictly by the book, you will want to utilize a measurement receiver or spectrum analyzer that fully complies with CISPR 16-1-1.
