Abstract
Disclosed is a digital phase-locked-loop including: a time-to-digital converter (TDC) configured to output a digital bit based on an input clock and a reference clock, in which the TDC includes: a first arbiter group configured to compensate for a phase difference between the input clock and the reference clock with a first average offset and output a first logic value; a second arbiter group configured to compensate for a phase difference between the input clock and the reference clock with a second average offset and output a second logic value; and a signal processor configured to output the digital bit based on the first and second logic values.
