Abstract

PURPOSE: To establish the multi-voltage generation circuit and the A-D converter using it with a simple constitution, with the combination of the storage charge in a plurality of capacitors.
CONSTITUTION: The first switching MISFET Q1 to charge up the first capacitor C1 to a given value, second switching MISFET Q2 to charge up the second capacitor C2 to the given voltage, third switching MISFET Q3 to discharge the capacitor C2, and fourth switching MISFET Q4 and Q5 placed between the charge and discharge terminals of the first and second capacitors C1 and C2 are provided. The charging voltage of capacitors C1 and C2 after the operation of the first to fourth switching FET's is taken as the output
