This paper describes a unified method to quantify and compare amplitude and phase noise induced by white and colored noise sources in electrical oscillators. The proposed approach relies on the Floquet theory of linear time-varying systems and on the application of averaging techniques to simplify the stochastic equations. Closed-form expressions for the phase and amplitude power spectrum are provided. These results are validated via comparisons with SpectreRF simulations and measurements.

Abstract
This paper describes a unified method to quantify and compare amplitude and phase noise induced by white and colored noise sources in electrical oscillators. The proposed approach relies on the Floquet theory of linear time-varying systems and on the application of averaging techniques to simplify the stochastic equations. Closed-form expressions for the phase and amplitude power spectrum are provided. These results are validated via comparisons with SpectreRF simulations and measurements.File in questo prodotto:
