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
Mixed-signal FPGA is here to stay! Programmable Logic DesignLine Blog 12/13/2005 Post a comment I've seen a number of devices that might be classed as "field-programmable analog arrays (FPAAs)" appear and disappear, but I think this one is here to stay...

Drones are, in essence, flying autonomous vehicles. Pros & cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight, as are piloted airplanes? Is the technology advancing faster than we can answer the questions it poses?
