Abstract: PURPOSE: A method for correcting a digital error of an analog/digital converter is provided to simplify an error correction process and minimize the power consumption by using a characteristic of a folding signal to divide a region of low bits and correcting errors of high bits according to the divided regions. CONSTITUTION: A low bit coding region is divided into four regions according to an odd number state and an even number state of predicting high bits. A coding process for low bits is performed. A coded result of the low bits is compared with the state of predictive high bits. The sum of the coded low bits and the predicting high bits is outputted if the coded result of the low bits corresponds to the state of predictive high bits. The sum of the coded low bits and the corrected high bits is outputted if the coded result of the low bits does not correspond to the state of predictive high bits.
