Modified Rational Function Modeling for Multi-Port High-Speed Differential Circuits
This paper presents a modified rational function modeling technique for multi-port high-speed differential circuit simulations,it models the differential channel and multiaggressor crosstalk with modified rational functions extracted from the single-ended multi-port S-parameters of the circuit. The multi-port S-parameters of a high-speed circuit can be directly measured or simulated using electromagnetic simulators,and the poles and residues of the modified rational functions are determined by a vector fitting algorithm. Compared to the traditional rational function modeling,far fewer poles are needed to model a channel and crosstalk. With the modified rational function modeling technique,the output signals of the differential channel and crosstaik can be expressedInclosed forms,providing a simple way to do quasi-analytic time-domain analysis of multi-port differential structures. The presented modeling technique is demonstrated for a 16-port high-speed electrical backplane.
