Rational models must be passive in order to avoid unstable time domain simulations. This
paper introduces a fast approach for passivity enforcement of pole-residue models. This is …

One major difficulty in the rational modeling of linear systems is that the obtained model can
be nonpassive, thereby leading to unstable simulations. The model's passivity properties are …

This paper introduces a new approach for rational macromodeling of multiport devices that
ensures high accuracy with arbitrary terminal conditions. This is achieved by reformulating …

Common design and verification flows of electronic systems under Signal and/or Power
Integrity (SI/PI) constraints often rely on the availability of accurate macromodels of …

Residue perturbation (RP) is often used a means for enforcing passivity of rational models.
One RP version combines a least squares problem with a constraints part and solves via …

SoFT is a new method and tool which measures and models linear electrical network
components in a wide frequency band with unprecedented accuracy. This is achieved by a …

Vector Fitting is employed to approximate the Frequency Response Analysis (FRA)
measurement data of a 13.8 kV/136.8 kV, 50-MVA single phase transformer. The frequency …

This paper describes a novel approach for electromagnetic transient simulations of
frequency-dependent network equivalents featuring variable time-step length along the …

This paper applies a constant, real modal transformation matrix to delay-less rational
modeling of multi-conductor interconnects. The modeling boils down to fitting and passivity …

Residue perturbation is used for enforcing passivity of a linear response model of an
electrical component having n> 1 ports. According to an exemplary embodiment, a modal …
