Abstract

PURPOSE:To obtain a desired charge and discharge linearity against an input value, and also to obtain a uniform output characteristic, by a simple constitution, by charging and discharging a capacitor while comparing in order an output value and an input value. CONSTITUTION:A value Vi to be sampled and output voltage Vo of a sample holding circuit 1 are compared by a comparator 11. In case of Vi>Vo, an output characteristic of the comparator 1 is ''+'', a diode D1 of a discriminator 12 conducts, a transistor TRQ1 of a bipolar rectifying circuit 18 onducts, a half-wave of an AC power supply 17 is inputted to the circuit 1, and its capacitor is charged. On the contrary, in case of Vi<Vo, when the output characteristic of the comparator 11 is ''-'', a diode D2 conducts, a TRQ2 conducts, the other half-wave of the electric power supply 17 is inputted to the circuit 1, and charge of the capacitor is discharged. Also, in case of Vi=Vo, the output characteristic of the comparator 11 becomes ''0'', the discriminator 12 is not operated and the capacitor is held by its potential.
