“…Considering a constant increase of integration densities, having a possibility of performing fast and accurate system-level simulations in an early design stage and optimizing its performance is of increasing importance. Connectors are typically modeled by multisegment lumpedelements as in [1], [3]- [7] or multisegment transmission lines as in [8]- [10]. In all of these papers, the model parameters are fitted to the measured data, either the S-parameter measurements as in [3], the time-domain reflectometry (TDR) as in [4], [6]- [9], or both as in [1] and [5].…”

Modeling of two high-current card-edge connectors is presented. The modeling methodology consists of dividing the connectors into uniform segments and modeling each segment by a multiconductor transmission line. The calculation of the per-unit-length parameters of each segment is based on the analytic expression for a generalized capacitance matrix of widely sepa-rated conductors. The proposed modeling methodology generates the circuit model solely from the geometrical parameters of the con-nectors without the need to perform measurements and/or electro-magnetic simulations. The modeling methodology is applied to two 62-pin high-current card-edge connectors that are used in the mea-surement setup for characterization of radiated electromagnetic emission of switched-mode power converters. Two printed circuit boards are designed to characterize the connectors and to vali-date the modeling methodology. The model of the complete char-acterization setup shows good agreement with the Sparameter measurements up to 3 GHz.
