Radio-frequency (RF) circuits exhibit several distinguishing characteristics that make them
difficult to simulate using traditional SPICE transient analysis. The various extensions to the …

In this paper, we present a methodology for generating guaranteed passive time-domain
models of subsystems described by tabulated frequency-domain data obtained through …

Passive macromodeling of high-speed package and interconnect modules characterized by
measured/simulated data has generated immense interest during the recent years. This …

With the continually increasing operating frequencies, complex high-speed interconnect and
package modules require characterization based on measured/simulated data. Several …

Automatic model reduction of chip, package, and board interconnect is now typically
accomplished using moment-matching techniques, where the matching procedure is …

udy the perturbation theory of structured matrices under structured rank one perturbations,
and then focus on several classes of complex matrices. Generic Jordan structures of …

Motivated by the analysis of passive control systems, we undertake a detailed perturbation
analysis of Hamiltonian matrices that have eigenvalues on the imaginary axis. We construct …

In the past decade, substrate noise has had a constant and significant impact on the design
of analog and mixed-signal integrated circuits. Only recently, with advances in chip …

We construct optimally robust port-Hamiltonian realizations of a given rational transfer
function that represents a passive system. We show that the realization with a maximal …

In this paper an optimization based model order reduction (MOR) framework is proposed.
The method involves setting up a quasiconvex program that explicitly minimizes a relaxation …
