ABSTRACT:
An improved clock signal modeling circuit capable of more quickly generating an internal clock signal in an external clock signal without using a phase locked loop and a delay locked loop, which includes a delay unit for receiving an external clock signal and for outputting a delay clock signal; a sampling unit for receiving the delay clock signal and for sampling in accordance with an external clock signal; a comparing unit for receiving the output of the sampling unit and for sequentially comparing the output; and an output unit for receiving the delay clock signal outputted from the delay unit and for outputting an internal clock signal in accordance with an output signal of the comparing unit and an externally applied switching signal.
