  • Patent number: 11894102
    Abstract: A duty correction device includes a clock generation circuit, first and second correction pulse generation circuits, and a duty correction circuit. The clock generation circuit generates first to third divided clock signals, each having a phase offset from a reference clock signal. The first correction pulse generation circuit generates a first correction pulse by detecting a phase difference between a delayed clock signal and the first and second divided clock signals. The second correction pulse generation circuit generates a second correction pulse by detecting a phase difference between the second and third divided clock signals. The duty correction circuit checks whether the first and second correction pulses are generated at a preset logic level of the reference clock signal, and reflects the first or second correction pulses in a duty correction operation for the reference clock signal according to a result of the check.
