View the effects of phase noise on a 10 MHz sine wave by using a spectrum analyzer. Adjust the resolution bandwidth of the spectrum analyzer to see its impact on the visualized spectral noise. Initialize variables for the simulation. Get fc = 1e6; % Carrier frequency in Hz fs = 4e6; ...
Period jitter is the variation in the period of the oscillator output signal. You can mathematically measure the period jitter directly, for instance in a time-domain simulation. You can then calculate the phase noise directly from the measured period jitter. When phase noise is determined in thi...

Readers will gain a deep understanding of ADPLLs and the central role played by noise-shaping. A range of ADPLL and TDC architectures are presented in unified manner. Analytical and simulation tools are discussed in detail. Matlab code is included that can be reused to design, simulate and ...
Modelling and Estimating Phase Noise with MatlabThe goal of this chapter is to illustrate how to model and estimate the phase noise of a sampled signal using Matlab. We first illustrate how the phase noise of a signal is related to the phase...doi:10.1007/978-3-319-03659-5_7...
