Multilayered power-ground (PG) planes are commonly used to supply power to circuits in high-speed electronic packages and printed circuit boards (PCBs). In this paper, we propose an efficient integral equation equivalent network method to simulate the interference produced by the rerouted return currents of signal traces inside such PG planes. The integral equation is created based on the geometrical features of the PG planes. Therefore, it could reduce the computing time and will be maintaining good accuracy…
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.
