A unified approach for the linear and nonlinear stability analysis of microwave circuits using commercially available tools

For the first time, an exhaustive linear and nonlinear stability analysis of multitransistors monolithic-microwave integrated-circuit (MMIC) circuits is presented. A key point of the proposed stability analysis lies in that it can be easily implemented on any computer-aided design (CAD) software. The presented approach allows both linear and nonlinear stability analysis of any complex circuit fed by small or large signals. Two examples are given...
