A time-domain method for numerical noise analysis of oscillators

A numerical noise analysis method for oscillators is proposed. Noise sources are usually small and can be considered as perturbations to a large amplitude oscillation. Transfer functions from each noise source to the oscillator output can be calculated by modeling the oscillator as a linear periodic time-varying circuit. The proposed method is a time domain method and can be applied to strongly nonlinear circuits. Thermal noise, shot noise and flicker noise are considered as noise sources. Error in the time domain method is also discussed.
