Abstract
A data processor includes: a reference signal generator generating a reference signal that gradually varies to enhance an amplitude of the processing signal; a comparator comparing the processing signal with the reference signal generated by the reference signal generator; a count period controller determining to perform a real number count operation or a complement number count operation; a counter performing the count operation during the count period determined by the count period controller and acquiring a predetermined level of digital data by storing the count value at the time of completion of the count operation; and a corrector acquiring the digital data as a value of a real number by correcting the complement number count operation. The count period controller independently controls the real number count operation and the complement number count operation of the counter on the basis of a predetermined criterion.
