Abstract

An ILFD control unit sets a control parameter of an injection locked frequency divider based on each frequency of a reference signal and a frequency-divided signal measured in response to the control parameter of the injection locked frequency divider, in a stop state of a VCO and an injection locked frequency divider. The ILFD control unit runs the injection locked frequency divider and sets a control parameter of the injection locked frequency divider based on each frequency of the reference signal and the frequency-divided signal measured in response to the control parameter of the injection locked frequency divider, in the stop state of the VCO.
