Abstract
In one embodiment of the invention, a method and a system for phase noise analysis of oscillators is provided using frequency aware perturbation projection vector techniques. The method and system includes performing steady state analysis on the oscillator by generating an augmented Jacobian matrix. A transfer function for frequency deviation is extracted for the augmented Jacobian matrix for a predetermined frequency range including the oscillation frequency of the oscillator. The phase noise is predicted based on the extracted transfer function.
