Title:
PHASE SYNCHRONIZATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/230292
Kind Code:
A1
Abstract:
A phase synchronization device generates a third signal having an intermediate phase between a first signal based on a reference signal and a second signal subjected to phase-shifting by an element of a former-stage, outputs a signal obtained by phase-shifting the third signal by a first phase shift amount as the second signal to an element of a later-stage, detects a phase difference between the third signal and a fourth signal obtained by phase-shifting the first signal outputted from the element of the later-stage by the first phase shift amount, and controls the first phase shift amount on the basis of the detected phase difference.
