A cad tool for automatic formulation of symbolic state equations of oscillating circuits

Beam steering using the synchronization has been highly studied in systems of oscillators. Thus the techniques used to analyze and understand the behavior of coupled microwave oscillators advanced. A new approach to analyze such systems based on the state-space representation is introduced in the paper. A very efficient method implemented on computer to automatically formulate the state equations in symbolic or numeric-symbolic form for the autonomous circuits like the oscillating circuits is presented and an illustrative example is done.
