The electric field is analyzed in a three-dimensional, inhomogeneously-filled stripline structure. The spectral domain technique is first used to obtain the field expressions in the spectral domain. Analytically performing the two-dimensional inverse Fourier transform results in electric fields that are expressed as closed-form solutions in terms of special functions that are free from any numerical integration. The closed-form solutions permit efficient, accurate full-wave simulations for packaging structures. Computational results for the fields are presented and the physical phenomenology of the fields is studied.

Three-dimensional TEM cells are starting to be used for EMC immunity testing and radiation measurements. In the second case, these new test facilities offer the advantage of not having to place the equipment under test in different positions to obtain its total radiated power or its far-field radiation pattern. After a brief overview of the general concept of 3D-TEM cells followed by a summary on radiation measurements in TEM and GTEM cells, the second part of this paper presents the practical application of radiation measurements of off-the-shelf electronic equipment using an industrial prototype of a 6-plate 3D-TEM cell. The results are then compared to reference results obtained of a conventional symmetrical TEM cell. This paper concludes with the repeatability and reproducibility of results obtained and the possibilities of measuring radiation from very small items such as electronic components.

This paper discusses a method for extracting the frequency dependent characteristic impedance of transmission lines from Time Domain Reflectometry (TDR) measurements using an Open, Short, Load, and Shortline calibration. The frequency dependent behavior of transmission lines was successfully captured using this method. Two types of transmission lines were measured using this method namely, thick metal transmission lines in Printed Wiring Board (PWB) and thin transmission lines in MCM-L technology.

A method is presented in which a geometry and frequency dependent precalculation of large pin count flat package ground plane currents is made. We use this precalculation to construct an adaptive non-orthogonal PEEC grid for correct modeling of inductance behaviour of RF packages with minimal ground plane discretisations needed.

This paper describes an electrical design optimization methodology for a high-speed point-to-point source-synchronous simultaneous bidirectional interface. These physical links are typically used to interconnect multiple processor subsystems to build symmetric multi-processor (SMP) systems, as well as to connect input/output (I/O) subsystems across relatively long distances. Major design issues such as attenuation, crosstalk, delay skew, impedance control and inter-symbol interference (ISI) are discussed for long and parallel external interconnections.

The CEMPIE approach, a circuit extraction technique based on a mixed-potential integral equation, has been applied to model multi-layer structures including power and signal layers. Power-bus noise mitigation effects due to a decoupling capacitor were studied for several cases with different spacing between the capacitor and an integrated circuit (IC). Modeling results indicate that the capacitor sharing a common via with the IC power/ground pins is superior; viz., it results in the lowest power-bus noise under similar conditions.

As bus speed targets rise and power supply voltages shrink, the traditionally separate procedures of I/O power delivery design and I/O signaling design must be brought together to comprehend the tight interaction between the two domains. The impact of the frequency-dependent, nonideal behavior of the power delivery system upon the I/O signal integrity and timing must be accurately predicted, rather than loosely guardbanded. This paper describes an efficient way of including these effects in the standard signal integrity and timing bus design process without compromising the speed of simulation.

The development of integrated passive components suitable for integration with printed wiring boards is relatively recent. This integration is required since in most mixed signal designs, off-passive components take up more real estate on the boards than the analog and digital signal processing units. Besides utilizing real estate on board, embedded passives on organic laminates significantly reduce cost and if optimized have less parasitics compared to discrete passive components. This paper discusses the design of high Q coplanar waveguide (CPW) planar inductors on laminates. The reason for choosing a CPW type layout is the ease in adding shunt elements and series elements compared to stripline and microstrip configurations. A max Q factor of 85 at 5.2 GHz was obtained for a 1.85 nH CPW type inductor. Several other inductors with similar performances were studied. The paper also presents a method to model the CPW type inductors. This approach allows designers to include metal-to-dielectric interface roughness, non-uniform signal line profiles and frequency dependent parameters such as the dielectric constant of materials.

Modeling of multiple via coupling is an important problem in the design of high-speed interconnect systems. It is known that the inter-via coupling has non-negligible effects on the signal integrity of high-speed circuits. In this paper, we investigate first order multi-via coupling based on a two-coupled-vias model. Analytical results are compared with experimental data up to 5GHz. Transient waveforms were obtained for reflection and transmission for trapezoidal and Gaussian input.
