A new stability criterion for negative resistance oscillators based on X-parameters

摘要

In this study, the stability analysis of oscillation is discussed based on X-parameters which provide a good performance for behavioral modeling in large-signal regime. A normalized criterion is introduced using the perturbation theory and Kurokawa approach. This criterion also accounts for the frequency dependency of nonlinear network. The proposed criterion is applied to the stability analysis of a negative resistance transistor based oscillator.
