I suppose everything old becomes new if you wait long enough. Two-stage (or more) power supply filtering was the norm for some 50 years in vacuum-tube radios. But scaling for frequency and current does require a bit of work. The quality of circuit simulator results ALWAYS depends on the quality of the component models. It takes great wisdom to know when you can ignore any of a component's parasitics. The old axiom is, of course, "garbage in, garbage out."
Don't forget: Spice lies! (Courtesy of Bob Pease ;-)
So, there is no clue here about inductor parasitics and other component side effects. Does not care, as long as you know what you're doing. Wuerth shortly will publish a book how to use LTspice with proper inductor and transformer models. Very promising! I love those new goodies to play with, I heard march next year.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
