ABSTRACT:
A resistance hybrid is disclosed including m+1 unit resistors connected in series, to further be connected in series between two resistance elements, one Rbottom and the other Rtop. Each unit resistor SBn includes an error correction resistance element R1dn and a set resistance element RTn connected in series, and further connected in parallel to a fuse RLn. In addition, the error correction resistance element R1dn is formed such that the combined resistance of the fuse RLn, set resistance element RTn, and error correction resistance element R1dn, is equal to the resistance value of the error correction resistance element R1dn. The value of resistance of the unit resistor SBn after the disconnection increases by the resistance value of set resistance element RTn, to thereby obviating the error possibly caused by the disconnection, which is originated from the resistance value of the fuse RLn. The resistance error caused by the disconnection can be reduced in the present resistance hybrid without appreciable increase in the resistance area, which is particularly advantageous in use for analogue circuits in various semiconductor integrated circuits such as voltage detection and constant voltage generating circuits.
