Abstract

PURPOSE:To realize a highly accurate A/D converter with simple constitution by applying a common input signal having a smaller relative offset level in comparison with the same common input signal or dynamic range to an input of plural unit analog digital converters so as to output sum of outputs. CONSTITUTION:In taking a sum 5 of outputs by connecting completely A/D converters 1, 2, 3, 4 of each unit in parallel, the output is increased by 2-bit. The increase in the accuracy is expressed by the addition theorem of noise as N<1/2>, where N is the number of unit A/D converters to be employed. Thus, the accuracy is increased by one bit.
