Document Type and Number:
WIPO Patent Application WO/2021/233203
Kind Code:
A1
Abstract:
A phase detection method, an apparatus thereof, and a device. The phase detection apparatus comprises a signal processing assembly, a phase discrimination component, and a phase comparison assembly. The signal processing assembly is configured to obtain a reference clock signal and an initial phase value thereof. The phase discrimination component is configured to obtain a clock signal to be measured, and obtain a first phase difference signal according to the reference clock signal and the clock signal to be measured. The phase comparison assembly is configured to obtain a phase adjustment signal according to the first phase difference signal. In addition, the signal processing assembly is also configured to perform phase adjustment on the reference clock signal according to the phase adjustment signal so as to reduce the first phase difference signal, add up the adjusted phase values so as to obtain a cumulative phase value, and obtain, according to the cumulative phase value and initial phase value, the phase value of the clock signal to be measured.
