ABSTRACT:
A delay locked loop (DLL) circuit comprising: a fundamental phase comparator for detecting a fundamental phase difference of two input signals; a delay circuit; a delay control circuit for adjusting a delay time of the delay circuit in response to an output signal of the fundamental phase comparator; and at least one further phase comparator for detecting a phase difference other than the fundamental phase difference such that an amount of change of the delay time is changed in accordance with the fundamental phase difference.
