MTL—A Multi-Wire Transmission Line Modeling Toolbox

Abstract

Abstract-Emerging wireline transmission systems aspire to deliver rates in the order of Gbit/s over short copper cables by exploiting higher frequencies and non-differential transmission modes. Reliable channel models are a prerequisite for system design and throughput predictions. In this paper, a MATLAB-based multi-wire transmission line modeling toolbox called MTL is presented. Based on Kelvin-model theory, MTL allows modeling of virtually any property (spanning the entire range from electrical properties such as voltages, currents, and impedances to system-level properties such as insertion loss or Shannon capacity) of multi-wire cables with arbitrary wire geometry. Compared to prior art, MTL allows exact computation of the capacitance matrix in a multi-wire system. Examples demonstrate the importance of this feature.

Characterization of Coupled Transmission Lines Used in Integrated Circuit Packaging on Printed Circuit Boards

“…However, this evaluation also leads to a degradation of signal quality and increase electromagnetic interference in the PCB cards. For that PCBs and their elements (edge connectors, microstrip lines), must be modeled using the transmission line methodology [1]- [4].…”
