@article{Demir1998PhaseNA, title={Phase noise and timing jitter in oscillators}, author={Alper Demir and Amit Mehrotra and Jaijeet S. Roychowdhury}, journal={Proceedings of the IEEE 1998 Custom Integrated Circuits Conference (Cat. No.98CH36143)}, year={1998}, pages={45-48} }

Phase noise is a topic of theoretical and practical interest in electronic circuits, as well as in other fields such as optics. Although progress has been made in understanding the phenomenon, there still remain significant gaps, both in its fundamental theory and in numerical techniques for its characterisation. We present a rigorous nonlinear analysis for phase noise in oscillators and reach the following conclusions: the power spectrum of an oscillator does not blow up at the carrier…
