  • Digital to time converter and digital to time converting method
    Patent number: 8462840
    Abstract: A digital-to-time converter for generating a first and a second output signal separated by a predetermined delay includes first and second periodic signal generators, respectively, generating a first and a second periodic signal, a periodic signal synchronizer detecting a phase difference between the first and the second periodic signals, and first and second output pulse generators, respectively, starting a count of the first and the second periodic signals when a phase of the first periodic signal coincides with a phase of the second periodic signal. When a first value is counted, the first output pulse generator outputs a pulse as the first output signal, and when a second value is counted, the second output pulse generator outputs a pulse as the second output signal.
