Nonlinear Analysis of Phase-Locked Loop
IFAC Proceedings Volumes, 2010Abstract New method for the rigorous mathematical nonlinear analysis of PLL systems is suggested. This method allows to calculate the characteristics of phase detectors and carry out a rigorous mathematical analysis of transient process and stability of the system.

Range Extension of a Phase-Locked Loop
IEEE Transactions on Communications, 1973The capture capability of a type of hybrid-locked loop (HLL) in a noisy environment has been shown to be better than that of a conventional phase-locked loop (PLL). An approximate method of estimating the locking range and the locking time of the HLL in the noisy environment has been presented. Also given are the experimental results in partial support

Arguably the most important circuit in modern electronics is a PLL. A PLL is embedded into virtually every piece of modern electronic equipment: computers, wireless communication systems, and test equipment, to name a few. What is more, each of the subsystem blocks inside these systems may contain their own PLL sub-circuit manufactured in an IC ...

Fractional-order phase-locked loop
2007 9th International Symposium on Signal Processing and Its Applications, 2007In this paper, a fractional-order analog phase-locked loop (FAPLL) model is proposed. In the new model, the traditional analog phase locked loop (APLL) is generalized by allowing the loop filters as well as the voltage controlled oscillators to acquire fractional order dynamics.

Review of Scientific Instruments, 2001
In this article, a phase-locked loop (PLL) is introduced. The proposed PLL, denoted by NPLL, is similar to the standard PLL except that it incorporates a nonlinear element and a low pass filter in its loop. The NPLL outperforms the standard PLL: (i) it has a large acquisition range, i.e., it can achieve locking in situations where the standard PLL ...

Phase/frequency detectors deliver output in the form of three-state, digital logic. Charge pumps are utilized to convert the timed logic levels into analog quantities for controlling the locked oscillators. This paper analyzes typical charge-pump circuits, identifies salient features, and provides equations and graphs for the design engineer.
