Abstract:
An disclosed analog/digital conversion apparatus for converting an analog signal into digital data by cycling the analog signal through a fully differential amplifier circuit includes a polarity switching unit configured to switch connection polarities of the fully differential amplifier circuit; and a control unit configured to control the polarity switching unit in such a manner that the connection polarities of the fully differential amplifier circuit are switched between a first signal cycle and second and subsequent signal cycles.
