Document Type and Number:
WIPO Patent Application WO/2019/127398
Kind Code:
A1
Abstract:
A phase alignment method and circuit. The phase alignment method comprises: acquiring multiple channels to undergo alignment; selecting one of the multiple channels to serve as a reference channel; determining correspondence relationships between phase shift values of respective target channels and output voltages; and performing, according to the correspondence relationships between the phase shift values of the respective target channels and the output voltages, adjustment of the phase shift values of the respective target channels. The method and circuit enable phase alignment to be performed on multiple channels, thereby solving a problem in the prior art in which no phase alignment method for multiple channels is available.
