<P>PROBLEM TO BE SOLVED: To correct an output offset voltage of a differential output circuit in circuit configuration that is small-sized and easily designed. <P>SOLUTION: The differential output circuit which performs data transmission by means of a differential current comprises: a first current source (11) for outputting an electric current to the outside of the circuit; a second current source (12) for introducing an electric current from the outside of the circuit; an output polarity switching circuit (13) for switching the polarity of the differential current generated by the first and second current sources; a voltage source (15) for supplying a predetermined voltage; and a resistor (15) connected between a predetermined node being interposed between the first and second current sources, and the voltage source. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
