Abstract
A time-to-digital converter includes first and second phase distribution circuits and N time-to-digital conversion circuits. The first and second phase distribution circuits each includes a plurality of frequency dividers connected in a tree structure. The first and second phase distribution circuits each divides a signal received by the frequency dividers of root nodes into N signals. The first and second phase distribution circuits each outputs the N signals each having a different phase. The N time-to-digital conversion circuits each converts a phase difference between an i-th signal (where i is an integer from 0 to N−1) that is output from the first phase distribution circuit and another i-th signal that is output from the second phase distribution circuit into a digital value.
