Title:
PHASE TRACKING CIRCUIT AND METHOD, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/055589
Kind Code:
A1
Abstract:
The present invention relates to a phase tracking circuit and method, and an electronic device. The phase tracking circuit may comprise: a frequency divider, which is used for performing frequency division processing on a first clock signal so as to obtain a carrier signal; a phase discriminator, which is used for comparing the phase of the carrier signal with the phase of a reference clock signal so as to generate a phase indication signal; a phase tuning module, which is used for adjusting the phase of the first clock signal on the basis of the phase indication signal, such that the phase of the carrier signal is closer to the phase of the reference clock signal; and a control module, which is used for controlling, on the basis of the phase indication signal, at least one of a running clock of the phase tuning module and a frequency dividing ratio of the frequency divider, so as to control the phase adjustment speed of the phase tuning module.
