Abstract

In this work we present a unified Brownian motion-based model for the dispersion in the RF spectrum of oscillators due to the phase and frequency noise processes. A novel analysis of the spectral dispersion due to random-walk frequency noise will be presented that shows the possibility of the existence of satellite peaks around the mainlobe of the RF spectrum, along with time-varying spectral broadening. Fourier Transform based models will be used for the even-order phase noise process, and fractional calculus based models will be used for the odd-order flicker phase and frequency processes. The generalised Gaussian function (GGF) is shown to be an appropriate model for the RF autocorrelation function in all cases.
