Macromodeling of Multiport Systems Using a Fast Implementation of the Vector Fitting Method (2008, methodology): “In the past few years, various enhancements like orthonormalization [3] and relaxation [4] have been proposed to improve the accuracy and convergence of this technique [5].”
Delay-Based Macromodeling of Long Interconnects From Frequency-Domain Terminal Responses (2010, background): “We remark that a delayed-rational form can also be obtained by replacing the partial fraction functions in (5) with polynomials or other systems of rational basis functions (such as orthogonal rational functions [6]).”
