Square Root Unscented Digital Phased-locked Loop
International Journal of Control, Automation and Systems, 2018Digital phase-locked loops (DPLLs) are widely used for synchronizing and estimating phase information. In DPLLs, the state estimator is a powerful method to estimate unknown phase information accurately. The Kalman filter (KF) is a well-known state estimator and has been employed to design DPLLs.

All Digital Phase-Locked Loops
1998In this chapter, we are going to extend our survey to loops that have do not have analog prototypes. Lindsey and Chie [1] performed a 1981 survey of digital PLLs that is recommended to the reader desiring additional architectures.

Self-calibration of digital phase-locked loops
Proceedings of CICC 97 - Custom Integrated Circuits Conference, 2002A novel method for the measurement of the jitter transfer function of digital phase-locked loops is presented. The signal generation and analysis circuits are entirely digital except for an extra charge-pump. They hence do not require calibration. Contrary to other phase-locked loop digital measurement schemes, a clock frequency larger than the phase ...

Digital phase locked loops for satellite communications
Proceedings of ICICS, 1997 International Conference on Information, Communications and Signal Processing. Theme: Trends in Information Systems Engineering and Wireless Multimedia Communications (Cat. No.97TH8237), 2002This paper documents an investigation into the behaviour of a digital phase locked loop which includes a hard limiter following the phase detector. The Chapman-Kolmogorov integral equation is utilised to allow calculation of the phase error density for both first and second order loops. Analytic results for the mean phase error and phase error variance

The paper reviews working principles of phase-locked loop and drawbacks of classical PLL structure in nanometric technologies. It is proposed to replace the classical structure by all-digital phase-locked loop structure. Authors described the main blocks of all-digital phase-locked loop (time to digital converter and digitally controlled oscillator ...
