ABSTRACT:
An analog-to-digital conversion method includes the steps of outputting an upper-bit conversion reference signal, obtaining a digital value of upper bits on the basis of a period of time from a set time to the time when a magnitude relation between the analog signal and the upper-bit conversion reference signal is determined to be changed, generating and outputting a lower-bit conversion reference signal, obtaining a digital value of lower bits on the basis of a period of time from a set time to the time when a magnitude relation between the analog signal and the lower-bit conversion reference signal is determined to be changed, and determining a digital value of digital data converted from the analog signal on the basis of the digital value of the upper bits and the digital value of the lower bits.
