Harmonic-balance simulation of strongly nonlinear very large-size microwave circuits by inexact Newton methods

摘要

The paper introduces a new approach to harmonic-balance simulation, based on inexact Newton methods and iterative system-solving techniques. Storage and factorization of the Jacobian matrix are avoided, resulting in a dramatic drop of execution time and memory occupation. HB analyses with several tens of thousands unknowns become possible on ordinary workstations.
