CROSSTALK AND TRANSIENT ANALYSES OF HIGH-SPEED INTERCONNECTS AND PACKAGES

This paper presents a new method for the crosstalk and transient analyses of lossy interconnects with arbitrary termination circuits. In order to analyze an interconnect containing N signal conductors, we first derive closed-form formulas to determine its transfer functions, and then apply the inverse Fourier transform to obtain its time-domain pulse response functions. Two types of equivalent circuit models can be formulated once the pulse response functions of the interconnect are found. The circuit schematics of the models depend on the number of the signal conductors, irrespective of the physical parameters of the interconnect. These models are compatible with standard circuit simulation tools since they consist of linear resistive networks and linear-dependent sources only. Two example circuits are studied to examine the accuracy and efficiency of the present method.
