Graphical determinations for startup of oscillation in microwave two-port circuit design.

In this paper, the stability criteria are used to graphically determine the startup of oscillation in a Smith chart. This approach is suitable for slightly unstable circuits near the resonated frequency. In practice, an available design of a microwave two-port oscillator is presented here. © 1998 John Wiley & Sons, Inc. Microwave Opt Technol Lett 19: 144–149, 1998. [ABSTRACT FROM AUTHOR]
