Abstract
The purpose of this work is to add one more circuit into the PLL to define the lock condition. New types of PLL lock detectors, the principles of their operation, parametrical comparisons are presented. Presented circuits provide a simple design and independence from supply voltage (analog lock detector) or design automation (fully digital lock detector).
