Abstract: PURPOSE: A digital DLL(Delay Locked Loop) device capable of duty cycle correction and a method for correcting duty cycle are provided to correct duty error using a mixing circuit, and to generate an internal clock signal having a 50 % duty cycle. CONSTITUTION: A buffer(110) generates a clock input signal enabled at an edge of a clock by receiving an external clock signal. A delay line block(120) receives the above clock input signal, and delays the above clock input signal by receiving the first and the second comparison signal. A blend circuit(130) bypasses the first clock signal while the second clock signal is not enabled, and generates a blend clock signal having a middle phase of each falling edge by mixing the first clock signal and the second clock signal if the second clock signal is enabled, in the delay line block. A delay model unit(140) compensates time difference between a clock from the external and the internal clock by receiving the mixed clock signal, and generates a compensated clock signal. A direct phase sensor(150) generates the first comparison signal by comparing the external clock signal with the compensated clock signal, and outputs the first comparison signal to the delay line block. And a phase sensor(160) receives the first and the second clock signal, and generates the second comparison signal by sensing the phase and then outputs it to the delay line unit.
