Generalized distributed nonlinear device modeling for Krylov-subspace based microwave circuit analysis

摘要

The paper introduces a new approach to the description of microwave devices by distributed models of complex topology. Each model is treated as a nonlinear subcircuit arbitrarily described on a nodal basis and interacting with the rest of the network through a number of external ports. A suitable formulation of the model equations allows harmonic-balance analysis to be carried out in a most efficient way by Krylov-subspace methods.
