摘要：
This paper demonstrates the use of a Barycentric Vector Fitting algorithm for the modeling of broadband frequency responses. This algorithm reduces the computation time of the pole-identification step by exploiting the specific form of the barycentric interpolation formula. Numerical results confirm that this approach can lead to significant savings in terms of computation time, while preserving a good accuracy of the model. The effectiveness of the algorithm is shown by applying it to a 4-port board-to-board interconnect.
