Abstract :
We present a new and efficient approach to the simulation of accurate near-carrier phase noise in free-running microwave MESFET oscillators. First, a new kind of noise analysis model of the oscillators is proposed that contains a complete nonlinear noise model of the MESFET. Then an efficient algorithm is proposed to predict the accurate near-carrier phase noise in the microwave MESFET oscillators by the nonlinear current method. Examples of application prove that the new approach is suitable for microwave CAD and excellent in both efficiency and precision in predicting phase noise in the microwave MESFET oscillators
