Oscillator Flicker Phase Noise: A Tutorial

Near-carrier oscillator spectrum due to flicker and white noise

The effect of device noise on oscillator phase noise in a close vicinity of average oscillator frequency is analyzed. We show that for 1/f noise, the line shape of a free-running oscillator changes from power to approximately Gaussian function very close to the oscillator frequency. The Gaussian regime occurs when the relationship between device noise and oscillator spectrum is strongly nonline...

Oscillator Modeling and Phase Noise

Oscillator Modeling and Phase Noise by Brian Nguyen Limketkai Doctor of Philosophy in Engineering-Electrical Engineering and Computer Sciences University of California, Berkeley Professor Robert W. Brodersen, Chair Using a dynamical systems perspective, we develop a method to calculate phase noise in oscillators based on a particle diffusion model. Starting from the basic nonlinear equations of...

Low Phase Noise Voltage - Controlled Oscillator

Multiplicative Noise in Non-equilibrium Phase Transitions: A tutorial

Stochastic phenomena in which the noise amplitude is proportional to the fluctuating variable itself, usually called multiplicative noise, appear ubiquitously in physics, biology, economy and social sciences. The properties of spatially extended systems with this type of stochasticity, paying special attention to the non-equilibrium phase transitions these systems may exhibit, are reviewed here...

Vulnerability to Noise of a Phase-locked Oscillator Array

The eeect of noise on the in-phase attractor of a set of N globally coupled oscillators is studied; these discrete-time maps are associated with the continuous-time equations of motion for a series array of Josephson junction oscillators. We investigate both geometrical properties of the basin of attraction in the large N limit, and the implications of this geometry on the average time for the ...
