ABSTRACT:
An integrated circuit includes a circuit chip, one or more circuits provided on the circuit chip, an input/output circuit provided on the circuit chip in electrical connection to the one or more circuits for transmitting and/or receiving an information signal to and from an external circuit outside the circuit chip, a plurality of resistance areas provided on the circuit chip for electrical connnection therewith for providing a predetermined input and/or output impedance of the integrated circuit, and a plurality of connection pads provided on the circuit chip in correspondence to the plurality of resistance areas for electrical connection therewith, for electrical connection to the external circuit. The plurality of resistance areas include a plurality of elongated resistance strips connected in series and extending parallel with each other, wherein each elongated resistance strip in each resistance area extends on the major surface of the circuit chip in a predetermined direction.
