Description

In this book an analytic treatment of Phase Noise in oscillators is given. Langevin equations for both white noise and flicker noise are analysed. The book starts with an introduction to the topic and introduces the reader to various models like LTI and LTV models. For white noise simple Langevin equations are dveloped which then lead to simple closed form solutions. For flicker noise a trap level model is used for the analysis. The analysis results in closed form expressions with certain approximations. The contribution of buffer or output stage of an oscillator is also analyzed. The proposed model is compared with a popular harmonic balance simulator and a reasonable agreement is obtained between simulator and theory.
