How to Fight Magnetic Noise Gremlins

Have you ever had a noise-sensitive circuit and tried to find the noise source? Even after you completely encased sensitive portions in all sorts of shielding, you still had noise? It’s very... [more]

An Intuitive Approach to Understanding Basic High-Speed Layout

What is a wire? At high speeds, it behaves very differently from what we were taught in college. This presentation on high-speed basics makes the subject intuitive in a way that’s easily understood.... [more]
