Noise tolerant oscillator design using perturbation projection vector analysis

The impact of an oscillatorpsilas intrinsic and extrinsic noise sources on its noise performance is evaluated using the perturbation projection vector (PPV) analysis. The projection of a perturbation into the phase deviation for white and flicker noise, as well as for deterministic perturbations is explained qualitatively. The PPV analysis is then applied to two ring-type voltage controlled oscillators (VCO). Comparisons with measured results demonstrate the usefulness of the PPV analysis for design of noise tolerant oscillators.
