Microwave Oscillator Design by State-Of-The-Art Nonlinear CAD Techniques

The paper introduces a systematic approach to the design of microwave oscillators, whereby the capabilities of state-of-the-art nonlinear CAD techniques are fully exploited. A true numerical optimization yields the active device bias point and the embedding network topology for optimum oscillator performance. The harmonic content of the oscillator waveforms and the actual frequency dependence of the linear subnetwork are accounted for with no limitations. A global stability analysis of the optimized circuit ensures both the operating-point stability and the oscillation buildup in the biased network.
