Abstract

PURPOSE: To reduce the conversion time and to enable high speed, by measuring the time until the changed potential and the specified potential are in agreement and determining unknown potential, after the potential of the first FET starts changing.
CONSTITUTION: The inverter INV converts unknown potential Vx into a suitable potential, and FETT2 changes the potential converted with the inverter INV by a given potential for a given time. Further, FETT3 changes the changed potential with the potential changing means by a given potential for a given time, and the comparison circuit CMP compares the potential changes by FETT2, T3 with a given potential. In this case, after the potential converted with the inverter INV with FETT2, the potential change by FETT2 is stopped and it is changed with FETT2. Further, after FETT2 starts the potential change, the time the changed potential and the specified potential are in agreement is measured to determine the unknown potential Vx. Thus, the conversion time can be reduced and high speed can be achieved.
