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."

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.
Blog Doing Math in FPGAs Tom Burke 13 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
