From Network Theory Towards Field Theory for (M)MIC Chip Level Simulation

A new iterative electromagnetic approach based on the Spectral Domain Technique (SDT) is presented which provides a consistent and rigorous methodology for the simulation of full (M) MICs moving from network theory towards field theory. This approach is related to previously published diakoptic techniques but differs in the way how partial electromagnetic solutions are generated and superimposed. In addition, it allows to move in a single step from approximate results neglecting coupling to solutions fully taking into account all parasitic coupling across a chip. The computational effort associated is equal to that of analyzing the N components of a circuit separately at the low end and is only slightly more than 2N with all first order coupling effects included which in practise is very close to the rigorous solution. The background of this approach is outlined and its validity is demonstrated by various examples.
