【 摘 要 】

This paper presents a new technique for parametric macro-modeling of tabulated S parameter data in frequency domain. The traditional technique is modified in such a way that barycentric interpolation is performed at residues of root models, rather than the whole root models. It avoids increasing the number of poles which represents the model complexity and makes the parametric macro-model more compact. An illustrative example involving a low-pass filter is presented for validation of the proposed method.
