Abstract :
Linear time variant (LTV) model is capable of making accurate predictions about phase noise in electrical oscillators, on the assumption that current-phase relation is linear. Unfortunately, this linearity assumption is not valid in the presence of high-power environmental noise. The proposed nonlinear time variant (NLTV) model modifies the existing LTV model, considering phase response saturation in electrical oscillators. The accuracy of this model is verified through the simulation of a colpitts oscillator using
