Title:
PHASE-SYNCHRONIZING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2020/217388
Kind Code:
A1
Abstract:
The present invention addresses the problem with conventional phase-synchronizing circuits, which is that the phases of an input signal and an output signal cannot be matched. A phase-synchronizing circuit according to the present invention comprises: a signal source that outputs a signal; a signal separator that outputs some of the signals outputted by the signal source as a transmission signal, and to which a reflected signal of the transmission signal is inputted; a first phase controller that causes the phase of the transmission signal outputted by the signal separator to be changed in accordance with a control signal; a signal reflector that passes the transmission signal outputted by the first phase controller through and outputs same as an output signal, as well as outputting some of the output signals as a reflected signal; and a phase comparator to which some of the signals outputted by the signal source are inputted as reference signals, and which compares the phase of the reference signal with the phase of the reflected signal outputted by the signal reflector and routed via the first phase controller and the signal separator and outputs a control signal that corresponds to a difference in the phases to the first phase controller.
