Phase Noise and Jitter in CMOS Ring Oscillators

Abidi, A.A.·2006·IEEE Journal of Solid-State Circuits

Abstract

A simple, physically based analysis illustrate the noise processes in CMOS inverter-based and differential ring oscillators. A time-domain jitter calculation method is used to analyze the effects of white noise, while random VCO modulation most straightforwardly accounts for flicker (1/f) noise. Analysis shows that in differential ring oscillators, white noise in the differential pairs dominates the jitter and phase noise, whereas the phase noise due to flicker noise arises mainly from the tail current control circuit. This is validated by simulation and measurement. Straightforward expressions for period jitter and phase noise enable manual design of a ring oscillator to specifications, and guide the choice between ring and LC oscillator

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
