Introduction to Validation Test Concepts in a Mixed Signal ASIC

Traditionally, validation engineers of analog products have had to worry about one thing, their analog function. But with the advent of functional safety, the complexity in system design has increased, and functions once found only in digital devices are now making their way into analog devices as well. This leaves individuals with one question- how to validate?

Capacitors: Theory and Application

This article presents the fundamentals and application of capacitors. What is a capacitor, and how do we select them? Techniques of selecting capacitors and things to consider when using capacitors are highlighted. Both practical examples and simulation are used to demonstrate the key points.

System-Level Grounding

Grounding is often viewed from separate points of view - safety, ESD, or EMI.  This article combines all these aspects together so that practitioners can address grounding at the factories and in the laboratories in a comprehensive way.

SCIF and Radio Frequency Secured Facility Design

Secure facility designs often comingle ICS/ICD-705 and NSA 94-106 design requirements, creating project confusion with significant design and cost implications. This article focuses on bringing some clarity to the differences between ICS/ICD-705 design guidance and NSA 94-106 performance requirements. The related secure facility design and construction process is also reviewed.

RF Tech Tip: BNC Versus Threaded Connectors

The shielding performance of bayonet vs. threaded connectors is measured and some possibly surprising conclusions are drawn. Bayonet connectors – more useful than you might think.

Troubleshooting EMC Problems Like an MD

This article describes three troubleshooting methodologies doctors use to diagnose (troubleshoot) medical problems. These same techniques have proven useful in my own EMC consulting practice.
