    • A delay locked loop (DLL) circuit having a structure in which a method of performing duty cycle correction (DCC) using two DLLs and an intermediate phase composer and a method of performing DCC by forming a closed loop using a negative feedback are combined with each other is provided. The DLL circuit includes a first DLL for receiving an external clock signal and generating a first clock signal and a second DLL for receiving an external clock signal and generating a second clock signal. The first clock signal and the second clock signal are synchronized with an external clock signal. The DLL circuit further includes an intermediate phase generation circuit for receiving the first and second clock signals and generating an intermediate phase clock signal and a DCC loop for receiving the intermediate phase clock signal and generating an output clock signal. The intermediate phase clock signal has an intermediate phase between the phases of the first and second clock signals. The output clock signal is generated through correction of the duty cycle of the intermediate phase clock signal using a value obtained by integrating the output clock signal.

    • A delay locked loop circuit for improving the jitter index using a phase blender. The present delay locked loop circuit comprises a first delay circuit which receives an input clock signal in order to generate a first delayed input clock signal, and a second delay circuit which receives an input clock signal in order to generate a second delayed input clock signal. The first delayed input clock signal is an input clock signal delayed by a period determined according to a first delay control signal inputted to the first delay circuit. The second delayed input clock signal is an input clock signal delayed by a period determined according to a second delay control signal inputted to the second delay circuit. A phase blending circuit receives the first and second delayed input clock signals, blends the phases of the first and second delayed input clock signals, and generates a phase blended clock signal. In addition, a phase detection circuit is provided to receive a reference clock signal and the phase blended clock signal, generate a phase push signal PUSH in the case that the phase of the phase blended clock signal is ahead of that of the reference clock signal, and generate a phase pull signal PULL in the case that the phase of the phase blended clock signal is behind that of the reference clock signal.
