Efficient linear circuit analysis by Pade approximation via the Lanczos process
Peter Feldmann,Roland W. Freund +1 more
TL;DR: In this article, the Lanczos process is used to compute the Pade approximation of Laplace-domain transfer functions of large linear networks via a Lanczos Process (PVL) algorithm.
Journal ArticleDOI
QMR: a quasi-minimal residual method for non-Hermitian linear systems
TL;DR: A novel BCG-like approach, the quasi-minimal residual (QMR) method, which overcomes the problems of BCG is presented and how BCG iterates can be recovered stably from the QMR process is shown.
Journal ArticleDOI
A transpose-free quasi-minimal residual algorithm for non-Hermitian linear systems
TL;DR: The biconjugate gradient method for solving general non-Hermitian linear systems and its transpose-free variant, the conjugate gradients squared algorithm (CGS), both typically exhib...
Journal ArticleDOI
Iterative solution of linear systems
TL;DR: Recent advances in the field of iterative methods for solving large linear systems are reviewed, focusing on developments in the area of conjugate gradient-type algorithms and Krylov subspace methods for nonHermitian matrices.
Journal ArticleDOI
Krylov-subspace methods for reduced-order modeling in circuit simulation
TL;DR: The use of Krylov-subspace methods for generating reduced-order models of linear subcircuit models that preserve the passivity of linear RLC subcircuits are described.
