ABSTRACT:
A delay-locked loop detector detects a control voltage of a delay-locked loop, in which the delay-locked loop generates an output clock signal according to a delay time that is controlled by the control voltage. The delay-locked loop detector includes a voltage detector, a switch, and a counter. The voltage detector detects the control voltage. The switch passes the control voltage to the voltage detector. The counter counts a constant period of time, in which the counter enables the switch to pass the control voltage to the voltage detector after the constant period of time.
