Abstract:
A D/A converter range calibration system in an A/D converter structure including a set of comparators with associated calibrating D/A converters includes means (RCC) for determining the offset error range for the entire set of comparators and means (R-DAC) for adjusting the dynamic range of each calibrating D/A converter to this offset error range.
