ABSTRACT:
An apparatus for compensating for an error of a time-to-digital converter (TDC) is disclosed to receive a delay phase from a phase detector including the TDC and a phase error including a TDC error and compensate for the TDC error to have a time resolution higher by N times (N is a natural number). The apparatus includes: a fragmenting and multiplying unit fragmenting the delay phase by N times (N is a natural number) to generate first to (N−1)th fragmented delay phases; an adding unit adding each of the first to the (N−1)th fragmented delay phases to the phase error to generate first to (N−1)th phase errors; and a comparison unit acquiring a phase error compensation value nearest to an actual phase error from the phase error and the first to (N−1)th phase errors.
