Abstract
In a pipeline type A/D converter, a switch for sampling an analog potential signal has its other terminal in connection with an A/D converter, a D/A converter, a capacitor for subtraction. Even when frequency of the analog potential signal is raised such that input current is increased and a voltage drop is increased at the switch, there will be no error in the result of subtraction like in the conventional example where analog potential signal was directly input to A/D converter. Accordingly, a pipeline type A/D converter with low power dissipation and satisfactory frequency characteristics is obtained.
