ABSTRACT:
An apparatus for adjusting a clock signal, including: a clock multiplexing unit for receiving an external clock signal, an external clock bar signal and a feed-backed clock signal in order to select one of the external clock signal and the external clock bar signal as an output signal of the clock multiplexing unit based on a result of comparing a phase of the external clock signal with a phase of the feed-backed clock signal; and a delay locked loop (DLL) for generating a duty corrected clock signal and the feed-backed clock signal in response to the output signal of the clock multiplexing unit.
