This paper shows an approach for the broad-band modeling of passive power-supply filter structures, which may be applied to the virtual filter design. The most important advantage of this technique is the possibility of considering the parasitic and functional behavior of a power-supply filter in the same simulation. The approach provides a 3-D model of the filter structure based on a differential field solver. Moreover, the passive components are approximated by combined behavioral-physical 3-D models, which…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
