Tutorial on Discrete Time Phase Noise Modeling for Phase Locked Loops
نویسندگان
چکیده
Phase noise is one of the main impairments in wireless communications systems, due to its strong distortion of the transmitted signal. In this work, a discrete time phase noise model for simulation environments is proposed. This model can be used to obtain a better understanding of the effects of phase noise on the behavior of communications systems. It has already been shown that phase noise can be analytically described by stochastic differential equations. In this contribution numerical solutions for these stochastic differential equations are given for different types of phase locked loops, allowing for the generation of phase noise samples.

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...

This paper will present a tutorial on phase-locked loops from a control systems perspective. It will start with an introduction of the loop as a feedback control problem, with both the similarities and differences to traditional control problems. Chief among the differences is the necessary inclusion of two nonlinearities in the loop that are not parasitic, but essential to the loop’s operation...
