摘要：

This brief employs a perturbation phase-domain model to numerically investigate the phenomenon of frequency-shift induced by colored-noise in nonlinear oscillators. It is shown that colored-noise with frequency decaying spectrum tends to induce a frequency-shift phenomenon both in almost-linear oscillators and in nonlinear topologies such as ring oscillators. It is also, shown that the relevance of the phenomenon depends linearly on the noise variance.
