Abstract :
Several new terms are defined regarding the stability of operating points of circuits, and they are applied to circuits with two transistors. It is shown that if such a circuit has three operating points, one of them must always be unstable, regardless of the junction capacitor values across the junctions, while the other two can always be made stable by an appropriate choice of capacitor values. Similar results have been shown for two-transistor circuits processing fewer than three operating points
