    • 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.
    • 公开了用于补偿时间 - 数字转换器(TDC)的误差的装置,以从包括TDC的相位检测器和包括TDC误差的相位误差接收延迟相位并补偿TDC误差以具有时间 分辨率提高N倍(N是自然数)。 该装置包括:分段和乘法单元,将延迟相位分片N次(N是自然数),以产生第一到第(N-1)个分段延迟相位; 加法单元将第一到第(N-1)个分段延迟相位中的每一个相加到相位误差,以产生第一到第(N-1)个相位误差; 以及比较单元从相位误差和第一到第(N-1)个相位误差获取最接近实际相位误差的相位误差补偿值。
