This paper presents a new adaptive sampling strategy for the parametric macromodeling of -parameter-based frequency responses. It can be linked directly with the simulator to determine up front a sparse set of data samples that characterize the design space. This approach limits the overall simulation and macromodeling time. The resulting sample distribution can be fed into any kind of macromodeling...
This paper introduces a constrained vector fitting algorithm which can directly identify a passive driving point function (impedance or admittance) from frequency domain data. The proposed positive fractions vector fitting (PFVF) algorithm formulates the residue identification step as a convex programming problem, while the pole identification step follows the unaltered standard Vector Fitting procedure...
In this paper, we present an efficient and compact circuit netlist formulation for rational models. It is shown how to implement the method for several commercially available time domain solvers. Finally, an example is given describing the flow and procedures to follow in order to obtain a reliable and stable transient simulation.
Vector fitting is a rational approximation technique, which is frequently used to calculate accurate macromodels of electrical and electronical structures. The robustness of the technique is obtained by combining the use of a weighted iterative least squares scheme and a well-chosen partial fraction basis. It was discussed in that numerical problems may occur if poles of higher-order multiplicities...
