In this paper, Now, in the field of an integrated circuit, MOS technology is in use. Moreover, low voltage-ization of a circuit is also called for. Then, the switched-capacitor (SC) circuit technology which makes a large analog system possible in single MOS IC receives attention in this field. However, in case the technology is applied in the environment of low voltage operation, when a switch change, the output saturation by separating from the negative return of an operational amplifier must compensate the fault voltage ( spike ) generated owing to. In this research,SC technology was applied to the D/A conversion machine used in various places, and circuit analysis was performed on the theme of the spike compensation low voltage SC circulation type D/A conversion machine by parting reference voltage.
