Title:
PHASE-LOCKED LOOP, RADIO FREQUENCY TRANSCEIVER, AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/097508
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and provides a phase-locked loop, a radio frequency transceiver, and a communication device, for use in reducing the power consumption of a communication device in a discontinuous working scene. The phase-locked loop is used for: outputting a first local oscillator signal within a first period of time, the phase of the first local oscillator signal at an end moment of the first period of time being a first phase; disabling the first local oscillator signal within a second period of time; and outputting a second local oscillator signal within a third period of time, the first period of time, the second period of time, and the third period of time being three consecutive periods of time in sequence, the angular frequency of the second local oscillator signal being the same with that of the first local oscillator signal, the phase of the second local oscillator at a start moment of the third period of time being a second phase, a phase difference between the second phase and the first phase being equal to a product of the angular frequency and a time difference, and the time difference being a difference between the start moment of the third period of time and the end moment of the first period of time. Applying the phase-locked loop in the communication device can reduce the power consumption of the communication device in a discontinuous working scene.
