Abstract
A time-to-digital converter (TDC) includes a count logic and a digital core. The count logic generates a first sequence of counts representing a first sequence of edges of a first periodic signal, and a second sequence of counts representing a second sequence of edges of a second periodic signal. The digital core generates a sequence of outputs representing the phase differences between the first periodic signal and the second periodic signal from the first sequence of counts and the second sequence of counts. Each output is generated from a pair of successive edges of the first direction of one of the periodic signals and an individual one of the other periodic signal occurring between the pair, and the output is set equal to the minimum of difference of the individual one with the first value of the pair and the individual one with the second value of the pair.
