Abstract

PURPOSE: To reduce the fluctuation of an output voltage dependent upon a bias current at a hold time by adding a capacitor and a switch to an operational amplifier.
CONSTITUTION: Capacitor 10 to cancel the voltage fluctuation of capacitor 2 dependent upon the bias current at input end 6 of operational amplifier 1 with the self- voltage fluctuation dependent upon the bias current at input end 7 of operational amplifier 1 during a hold period and switch 11 which is connected in parallel to capacitor 10 and is switched synchronously with switch 3 are added. Then, the output voltage fluctuation during a hold period is restrained.
