Abstract :
This paper presents a signal processing technique called time-domain phase unwrapping applied to the measurement of phase noise in oscillators and which overcomes the dynamic range problem of using phase detectors. The technique can be applied also to the measurement of the amplitude noise of the oscillator. In this paper, the associated theories and the preliminary experimental results are included.
