ABSTRACT:
A delay locked loop (DLL) circuit includes a first feedback loop configured to delay a reference clock signal with a delay line, wherein the first feedback loop is further configured to generate a correction clock signal by correcting a duty cycle of the reference clock signal by adjusting a delay of the delay line; and a second feedback loop configured to generate an output clock signal by detecting a phase of the reference clock signal and delaying the correction clock signal with a delay according to the detection result.
