Abstract
A time-to-digital conversion circuit for converting a time difference between two input signals to a 1-bit digital value, and adjusting the time difference between the two input signals to generate two output signals includes: a phase comparator configured to compare phases of the two input signals with each other to generate the digital value; a phase selector configured to output one of the two input signals which has a leading phase as a first signal, and the other of the two input signals which has a lagging phase as a second signal; and a delay unit configured to output the first signal with a delay, wherein the time-to-digital conversion circuit outputs the signal output from the delay unit and the second signal as the two output signals.
