Abstract: PURPOSE: An analog to digital converter for high speed conversion is provided to minimize errors when an analog signal is converted into a digital signal and improve a nonlinear property. CONSTITUTION: An integrating part(200) integrates a difference between an input signal and an converted analog value which is converted from a digital output signal.

A shift controlling part(250) forms a shift control signal based on a digital output signal. A digital to analog converter(260) changes a digital output signal into an analog signal and forms a difference between the converted analog signal and the input signal.
