PHASE-LOCKED LOOP DEVICE WITH FEEDBACK BASED ON INTEGRATED MAXIMUM PRINCIPLE Russian patent published in 2015 - IPC H03L7/06 

FIELD: radio engineering, communication.

SUBSTANCE: device includes a reference generator; a tunable generator; an arcsin signal generating unit; a sign signal generating unit; a modulus generating unit; first, second, third, fourth, fifth, sixth and seventh product generating units; first and second sum generating units; an RC filter; an integrating scale converter; a derivative generating unit and a focusing link.

EFFECT: shorter capturing time compared to a phase-locked loop device with a single-link RC filter.
