Abstract :
Using the modern analysis tool Matlab, amplitude and phase noises have been extracted separately from the measured time domain output voltage of a sinusoidal oscillator. Analyzing the auto and cross correlations of the extracted amplitude and phase noises as functions of time, now we know how oscillator noise can be modeled for system analysis.
