A time domain behavioral model for oscillators considering flicker noise

摘要

The phase noise behavior due to flicker noise of an oscillator has not been modeled accurately by a time domain behavioral model. In this paper, the mathematical foundation to model the up-converted flicker noise region of the phase noise is discussed and derived in detail. Based on the foundation, we present a time domain behavioral model of the oscillator and implement it in Simulink. Comparisons show that the model is as precise as the direct transistor-level circuit simulation, whether in the up-converted thermal or flicker noise region.
