Abstract
A TDC measures a time difference between delay time that is in accordance with voltage variations. A DCOgenerates an oscillation signal having a cycle that is in accordance with an input signal. A frequency dividergenerates a divided signal by dividing the oscillation signal. An adderinputs, to the DCOa signal obtained by adding a second signal that changes an oscillation cycle of the DCOin accordance with the time difference measured by the TDC to a first signal that is in accordance with a phase difference between the divided signal and a reference signal. A control circuitobtains a measurement time resolution of the TDC and matches a cycle modulation time resolution of the DCOwith the measurement time resolution of the TDC.
