ABSTRACT:
An A/D conversion apparatus includes: a first and a second D/A converter to sample an analog signal and successively compare the analog signal and a reference signal to generate a first and a second comparison signal respectively; a first comparator to compare the first comparison signal generated by the first D/A converter with a benchmark signal; a second comparator to compare the second comparison signal generated by the second D/A converter with the benchmark signal; and a converter to convert the analog signal to a digital signal according to results of the comparisons by the first and second comparators.
