Apparatuses, methods, and duty cycle correction circuits are described. An example apparatus includes a duty cycle correction (DCC) adjustment circuit configured to receive an input signal, and to adjust a duty cycle of the input signal to provide an output signal. The DCC circuit including a coarse adjust control circuit configured to adjust the duty cycle of the input signal by a first amount that is equal to one or more unit adjustments, and a fine adjust control circuit that is configured to adjust the duty cycle of the input signal responsive to a pulse signal by a second amount that is less than the unit adjustment.
