Abstract
A digital phase detector utilizes a digital compartor and a plurality of delay elements. The comparator compares two signals and generates an output signal with a duration corresponding to the time delay between the arrival times of two signals. The output signal propagates through the plurality of delay elements. The number of delay elements that cover the duration of the output signal determine a time value for the duration of the output signal.
