Abstract

PURPOSE:To prevent a malfunction from being generated, by outputting a digital signal by comparing an analog signal input voltage directly with a reference voltage for bit from a reference voltage generation circuit for bit. CONSTITUTION:The reference voltage generation circuit Gn for n-th bit generates the reference voltage Vn for n-th bit expressed as Vn=Vi/2(where, Vi represents the maximum value of the analog signal input voltage). Meanwhile, the reference voltage generation circuit Gj for j-th bit (j=1, 2...(n-1)) generates the reference voltage Vj for j-th bit based on (j+1)-th...(j+2)-th...n-th bit digital signals obtained from the output terminals of comparators for (j+1)-th, (j+2)-th...n-th bit. In such a way, the malfunction can be prevented from occurring.
