Transformer Theory Made Simple Transformers used for 50/60 Hz power conversion must be physically larger than those used in wall-warts. Read this article and you will understand why. Read Article

Monte Carlo Simulation vs. Sensitivity Analysis: What’s the Difference? SPICE gives you an alternative to Monte Carlo analysis so that you can understand circuit sensitivity to variations in parameters. Read Article

The Basics of Monte Carlo in SPICE: Theory and Demo Anytime you place a component in your PCB, it’s almost like you’re gambling. All components have tolerances, and some of these are very precise (resistors for instance), but others components can have very wide tolerances on their nominal values (e.g., wirewound inductors or ferrites). In the event the tolerances on these components become too large, how can you predict how these tolerances will affect your circuits? While you could calculate Read Article
