Abstract
A time-interleaved A/D converter apparatus has a primary signal A/D converter circuit group that is time-interleaved with a combination of N A/D converter circuits, a correction signal generation part operable to receive the input analog signal and a 1/m-sampling signal having a speed that is 1/m of a rate of the sampling signal inputted to the primary signal A/D converter circuit group, to extract a dispersion of a transmission line that is immanent in the input analog signal, and to output the dispersion as a dispersion compensation control signal used for digital signal compensation, and a signal processing part operable to convert the N digital signals into one digital signal based upon the dispersion compensation control signal and to compensate a dispersion included in the converted digital signal.
