Abstract :
The paper discusses a new approach to the global stability analysis of large nonlinear microwave circuits for which Nyquist´s analysis is not usable owing to the size of the characteristic equation. Making use of a Krylov method for autonomous circuits, a state lying on the bifurcated branch close enough to the bifurcation may be efficiently located. The bifurcated branch may then be found by ordinary continuation.
