Numerical extraction of partial inductance of package reference (power/ground) planes

This paper presents a numerical approach for extracting the partial inductance of package reference (power/ground) planes using the finite element method. A simpler method is proposed to determine the partial inductance between two or three sources and sinks which are of importance in EMC/EMI considerations. An application is presented to verify the partial inductance obtained by R. Lee Hill et al (see Proc. IEEE Int. Symp. EMC, p.116-120, August 1994), where the partial inductance was modeled by a symmetrical coplanar circuit. Good agreement has been found between the numerical and theoretical results.
