Abstract
An analog-to-digital conversion device includes quantization circuits and binarization circuits. Each quantization circuit samples an input analog signal at a predetermined period to obtain a sample, quantizes the sample into a (n+1)-valued signal with n (n is an integer of two or more) thresholds, and outputs the quantized value. Each binarization circuit converts the (n+1)-valued quantized value output from the quantization circuit into a binary code.
