The Design of Low Noise Oscillators / Edition 1

by Ali Hajimiri, Thomas H. Lee

Overview

It is hardly a revelation to note that wireless and mobile communications have grown tremendously during the last few years. This growth has placed stringent requi- ments on channel spacing and, by implication, on the phase noise of oscillators. C- pounding the challenge has been a recent drive toward implementations of transceivers in CMOS, whose inferior 1/f noise performance has usually been thought to disqualify it from use in all but the lowest-performance oscillators. Low noise oscillators are also highly desired in the digital world, of course. The c- tinued drive toward higher clock frequencies translates into a demand for ev- decreasing jitter. Clearly, there is a need for a deep understanding of the fundamental mechanisms g- erning the process by which device, substrate, and supply noise turn into jitter and phase noise. Existing models generally offer only qualitative insights, however, and it has not always been clear why they are not quantitatively correct.

Editorial Reviews

Offers a new time-variant phase noise model capable of making quantitative predictions of the phase noise and jitter of different types of oscillators. Reviews the definition and modeling of frequency instabilities in electrical oscillators, and summarizes existing models for jitter and phase noise. Discusses prediction of jitter and phase noise of ring oscillators, and investigates the phase noise of differential LC oscillators. The model is generalized to multiple noise sources with arbitrary correlation and cyclostationarity.
