Title :
Oscillator phase noise: a tutorial
Author_Institution :
Stanford Univ., CA, USA
Abstract :
An understanding of how device noise becomes phase noise in practical oscillators is complicated by the presence of nonlinearities (for amplitude stabilization), and by the failure of time invariance. This tutorial reviews the qualitative insights of older (linear, time-invariant) models, and supplements those with powerful additional insights provided by a recently developed time-varying model. Among the most significant are the importance of symmetry in suppressing the upconversion of 1/f noise into noise near the carrier, and an appreciation of cyclostationary effects
