AUTOMATIC-GENERATION OF STARTING VALUES FOR THE SIMULATION OF MICROWAVE-OSCILLATORS BY FREQUENCY-DOMAIN TECHNIQUES

In this paper a new approach to the start-up problem inherent to the l arge-signal analysis of autonomous circuits in the frequency domain is presented. By insertion of a simple network, depending on one paramet er, the oscillator is damped to the stability limit where a linear ana lysis yields good results. The steady state of the undamped oscillator is then obtained by a continuation method corresponding to the succes sive removal of the damping network. With this procedure the degenerat e solution may be excluded in a straightforward manner.
