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

Which Type of Opto-Isolator Is Right For Your Circuit?
An optoisolator is an electronic device that can be used to pass information between a diode without passing an electrical current. Because there is no need to directly pass voltage or current between the inputs and outputs in an optoisolator circuit, these components can be used to provide electrical isolation in two regions in a PCB. Opto-isolators act as a protection mechanism, ensuring that harmful electrical currents cannot flow across the
