Jc. Liu et al., GRAPHICAL DETERMINATIONS FOR STARTUP OF OSCILLATION IN MICROWAVE 2-PORT CIRCUIT-DESIGN, Microwave and optical technology letters, 19(2), 1998, pp. 144-149
In this paper the stability criteria are used to graphically determine
the startup of oscillation in a Smith chart. This approach is suitabl
e for slightly unstable circuits near the resonated frequency In pract
ice an available design of a microwave two-port oscillator is presente
