Phase jitter dynamics of first-order digital phase-locked loops with frequency-modulated input [PDF]
, 2008 IEEE International Symposium on Circuits and Systems (ISCAS), Seattle, USA, 18-21 May 2008Inherent to digital phase-locked loops is frequency quantization in the number-controlled oscillator which prevents the loop from locking exactly onto its reference

A PLL Scheme for Synchronization with Grid Voltage Phasor in Active Power Filter Systems
Electrical, Control and Communication Engineering, 2010 Voltage source inverters connected to the grid in applications such as active power filters require synchronization with the grid voltage. Since in practice the grid voltage can be unbalanced and distorted, but the operation of the whole active filter ...

Radar Waveform Generator with Fuzzy Frequency Regulation [PDF]
International Journal of Telecommunications: The Phase-Locked Loop (PLL) is a common functional component in many electrical systems. Phase-locked loops (PLLs) are closed-loop feedback-driven devices producing a signal depending on the frequency and phase of reference sig-nal that comes in.

Statistical analysis of first-order bang-bang phase-locked loops using sign-dependent random-walk theory [PDF]
, 2010 Bang-bang phase-locked loops (BBPLLs) are inherently nonlinear due to the hard nonlinearity introduced by the binary phase detector (BPD). This paper provides an exact statistical analysis of the steady-state timing jitter in a first order BBPLL when ...

Structural Resemblance Between Droop Controllers and Phase-Locked Loops
IEEE Access, 2016 It is well known that droop control is fundamental to the operation of power systems and now the parallel operation of inverters, while phase-locked loops (PLLs) are widely adopted in modern electrical engineering.
