“…Recently, we found that this "imbalance-driven" mechanism is essentially equivalent to the current-driven mechanism. In this special session, we explain this identity and present some examples of common-mode evaluation [9]. The estimations agreed well with the measurements.…”

Some recent results from research conducted in the EMC group at Okayama Universiry are reviewed A scheme for power-bus modeling with an analytical method is introduced. A linear macro-model for ICdLSIs. called the LECCS model, has been developed for EM and EMS simulation. This model has a very simple structure and is suficiently accurate. Combining the LECCS model with analytical simulation techniques for power-bus resonance simulation provides a method for high-speed E M simulation and decoupling evaluation related to PCB and LSI design. A usefir explanation of the common-mode excitation mechanism, which utilizes the imbalancefactor of a transmission line, is also presented. Some of the results were investigated by implementingprototypes of a high-speed EM7 simulator, HISES.

“…In this paper, we review our recent results on power-bus modeling [5], ICLSI modeling [b], and EMYEMS and decoupling simulations with the LECCS mode1 [7,8]. We also model the common-mode excitation on a PCB with a narrow ground plane [9,10]. The common-mode model was implemented as another part of HISES and is also demonstrated here.…”
