Each of the phase detector cells (31,51,71,91) in a phase detector (2) has an input (32,52,72,92) connected to a node (11) and another input (33,53,73,93) connected to an output (35,55,75,95) of a corresponding delay cell (30,50,70,90) in a delay circuit (1). The phase detector is coupled to a control unit (4) that adjusts the delay time of the delay circuit by switching the delay cells. |
