    • A reference A/D conversion unit is connected in parallel to an input common to a time-interleaved A/D converter to be a calibration target, and the output of each unitary A/D conversion unit which makes up the time-interleaved A/D converter is calibrated in a digital region by using a low-speed high-resolution A/D conversion result output from the reference A/D conversion unit. Also, fCLK/N (fCLK represents an overall sampling rate of the time-interleaved A/D converter, and N is relatively prime to the number of unitary A/D conversion units connected in parallel M) is set as the operation clock frequency of the reference A/D conversion unit. Samplings of all unitary A/D conversion units can be sequentially synchronized with the sampling of the reference A/D conversion unit, and the operation clock frequency of the reference A/D converter can be made N times slower than the overall sampling rate of the time-interleaved A/D converter.
    • 参考A / D转换单元并联连接到时间交织的A / D转换器的公共端作为校准对象,并且构成时间交织的A / D转换单元的每个单位A / D转换单元的输出, D转换器通过使用从参考A / D转换单元输出的低速高分辨率A / D转换结果在数字区域进行校准。 另外,fCLK / N(fCLK表示时间交织的A / D转换器的总体采样率,N是并行连接的单位A / D转换单元的数量的N相对于M)被设定为操作时钟频率 参考A / D转换单元。 所有单位A / D转换单元的采样可以与参考A / D转换单元的采样顺序同步,并且参考A / D转换器的工作时钟频率可以比总的采样率慢 时间交织的A / D转换器。
