This paper discusses the analysis of embedded passive components using a rational polynomial approximation. The method combines the accuracy of full wave EM solvers with Cauchy's method to generate the interpolated response using a minimum number of frequency points. It is shown that the method is able to extract the resonance behaviors and quality factor (Q) of embedded passive components with minimum error.

The investigation on the relative significance of electromagnetic coupling between vias and parallel traces is presented in this paper. This study shows that the coupling between vias can often be stronger than the coupling between traces and is therefore not negligible in signal integrity analysis of high-speed electronic packages.

One of the main limitations for the application of the MCM approach is the factor of costs. This problem can be solved by using low cost PCB substrate material. It must be assured, that PCB materials can meet the demands on the interconnection parameter for MCM wiring systems. It is shown by measurement results, that the line impedance is in the required range for MCM application. However, the increase in wiring integration can be a handicap regarding the coupling factor.

The S/390 architecture lends itself to an MCM package solution that provides the best performance at the lowest cost for the maximum SMP system. In this paper we develop a cost performance criterion that can be used to evaluate several MCM structures and materials. The results of this comparison show that a Glass Ceramic based MCM is cost performance equivalent to a polyimide thin film based MCM for off chip bus speeds up to 250 MHz. At this range of frequency this work shows that an Alumina MCM implementation has 17% less cost performance. In addition, the trend curves shown in this study indicate that polyimide thin film MCM structures will be the best cost performers in future systems where the off chip bus speeds exceed 250 MHz.

This paper reports the use of two-dimensional numerical simulations in modeling the effects of packaging on the electrical performance of high-power modules. Non-isothermal simulations are performed to study the performance and failure of IGBTs under short-circuit and clamped inductive switching stress.

Method-of-Moments (MoM) based 3-D electromagnetic analysis programs typically generate dense systems of equations which are extremely expensive to solve. In the last several years, very fast MoM solvers have been developed by sparsifying the dense system using a hierarchy of multipole expansions or grid projection plus the fast Fourier transform. The hierarchical multipole algorithms represented clusters of source distributions with an expansion in the center of the cluster, where as grid projection algorithms represent clusters using grid-locked point sources. In this paper we consider how to improve the efficiency of either algorithm by using grid-locked multipole expansions to represent clusters of sources.

The list of system design concerns is growing to encompass additional electrical limitations as the frequency of operation increases. These limitations are being mitigated by increasing bus widths, added material costs, more complex technology, and some changes in physical architecture.

In this paper a technique is described for the measurement of the correct S-parameters of an N-port package or interconnection using a 2-port network analyzer with 50 /spl Omega/ system impedance and N imperfect terminations. The technique is fully general and can be applied using arbitrary terminations. Broadband 50 n loads are not required. The method is illustrated on a coupled microstrip line structure.
