Abstract

PURPOSE: To obtain a digital-analogue converter having a good conversion precision by making it possible to correct the capacity value of a reference capacity material in the conversion system, which uses a capacity row, etc., to perform the digital-analugue convesrion, after the completion of the production process.
CONSTITUTION: It is probable that capacity value C0 of reference capacity material 11 has error, and correcting capacity materials 12, 13 and 14 having capacities C1, C2 and C3 respectively are connected in series to insulating gate-type FETs 15, 16 and 17 respectively and are connected in parallel to reference capacity material 11. FETs 15, 16 and 17 can store the state of conduction or non-conduction in non- volatility according to the charge accumulation state of the floating gate. FET 15, 16 and 17 are selected by operating the charge accumulation state of one or plural floating gates of FETs 15, 16 and 17, which are in a non-conduction state under an initial state, from the external and are made into a conduction state, and correcting capacity materials connected in series to them are connected in parallel to capacity material 11 set previously, so that the capacity value taken in from terminals 18 and 19 of capacity material 11.
