Abstract
A delay locked loop includes a delay chain that contains a plurality of series-connected delay cells, a phase detector arrangement that contains a plurality of phase detector cells and a control unit. The delay locked loop delays an input signal by a delay time via the delay chain depending on the number of delay cells in the series that are activated for delay. The phase detector arrangement detects the phase of the signal at the output of each delay cell in the delay chain. The control unit activates a number Z of the delay cells of the delay chain based on the difference in phase of the original signal and the delayed signal.
