Comparison of the acquisition behaviour of phase-locked-loops with different comparators
, 2022 S.112-17Phase-locked-loops for synchronisation of analogous signals, pulses and codewords are based on the same principle. For realization different phase comparators can be used. The influence of six comparators on the acquisition behaviour is compared.

Synchronization in networks of mutually delay-coupled phase-locked loops
New Journal of Physics, 2014 Electronic components that perform tasks in a concerted way rely on a common time reference. For instance, parallel computing demands synchronous clocking of multiple cores or processors to reliably carry out joint computations.

Decentralized Adaptive Control With Virtual Inertia for Cascaded-Type VSGs
IEEE Open Journal of Power ElectronicsThis paper presents a decentralized adaptive control for cascaded-type virtual synchronous generators (CVSGs) in microgrids. By leveraging a frequency correction term derived from the local power derivative, the virtual inertia is adaptively adjusted ...

Power-efficient time-to-digital converter for all-digital frequency locked loops
, 2015 An 8-bit time-to-digital converter (TDC) for all-digital frequency-locked loops ispresented. The selected architecture uses a Vernier delay line where the commonlyused D flip-flops are replaced with a single enable transistor in the delay elements.This ...

International Journal of Electrical Power & Energy SystemsThe interaction of multi-time scale control loops between grid-following converters (GFLCs) based on phase-locked loop (PLL) synchronization and grid-forming converters (GFMCs) based on power synchronization introduces new instability risks. Based on the

Nanosecond channel-switching exact optical frequency synthesizer using an optical injection phase-locked loop (OIPLL) [PDF]
, 2004 Experimental results are reported on an optical frequency synthesizer for use in dynamic dense wavelength-division-multiplexing networks, based on a tuneable laser in an optical injection phase-locked loop for rapid wavelength locking.
