How to fully integrate switching DC-DC supplies with inductor multipliers Design How-To 12/19/2005 Post a comment In spite of the low noise, high speed, and simplicity of linear regulators, switching power supplies are increasingly more appealing to the designer because of better power efficiency and integration is also becoming practical. Unfortunately, building switching supplies that are almost as practical and simple as linear regulators is expensive. Here's what you need to know to use switching supplies.
Understanding LVDS Fail-Safe Circuits Design How-To 12/14/2005 Post a comment Low-voltage differential signaling (LVDS) is a widely used differential signaling technology for high-speed digital-signal interconnections. In many applications, the LVDS receiver needs a fail-safe function to avoid an uncertain output state when the input is connected improperly This article examines circuit design and performance characteristics of three popular fail-safe functions. Comparative analysis of circuit designs will guide designers in the use of fail-safe circuits for high-speed d
