Phase Noise and Jitter
نویسنده
چکیده
Phase noise and jitter are two related quantities associated with a noisy oscillator. Phase noise is a frequency-domain view of the noise spectrum around the oscillator signal, while jitter is a timedomain measure of the timing accuracy of the oscillator period. This paper discusses the relationship between phase noise and jitter in free-running oscillators. The reader is referred to three other papers for a more detailed look at the theory: Demir [1], Hajimiri [2] and Herzel [3]. The phase noise and jitter theory discussed here is mainly taken from these three papers. The jitter in a closed-loop phase-locked loop is not discussed here; see [4, 9, 10].

Dual Phase Detector Based Delay Locked Loop for High Speed Applications
In this paper a new architecture for delay locked loops will be presented. One of problems in phase-frequency detectors (PFD) is static phase offset or reset path delay. The proposed structure decreases the jitter resulted from PFD by switching two PFDs. In this new architecture, a conventional PFD is used before locking of DLL to decrease the amount of phase difference between input and outpu...
متن کاملPhase Statistics of Soliton
The characteristic function of soliton phase jitter is found analytically when the soliton is perturbed by amplifier noise. In additional to that from amplitude jitter, the nonlinear phase noise due to frequency and timing jitter is also analyzed. Because the nonlinear phase noise is not Gaussian distributed, the overall phase jitter is also non-Gaussian. For a fixed mean nonlinear phase shift,...

متن کاملModeling of Jitter Characteristics for the Second Order Bang-Bang CDR
Bang-Bang clock and data recovery (BBCDR) circuits are hard nonlinear systems due to the nonlinearity introduced by the binary phase detector (BPD). The specification of the CDR frequency response is determined by jitter tolerance and jitter transfer. In this paper, jitter transfer and jitter tolerance of the second-order BBCDR are characterized by formulating the time domain waveforms. As a re...
