Abstract: PURPOSE:To reduce the input bias current of a non-inverted terminal and to improve input resistance by providing a resistor and plural constant current sources, setting the current values of the respective constant current sources to set values and constituting an offset circuit. CONSTITUTION:At a resistor 10, a voltage V10=R10.I3 is generated by a current inputted from a third constant current source 8 on the input terminal side. The characteristics of third and fourth transistors 3 and 4 are sufficiently arranged. When the inverted terminal and non-inverted terminal of the OP amplifier are connected at the same potential such as zero volt, for example, the base potential of a first transistor 1 is turned to VBE, the base potential VBE of a second transistor 2 is turned to (VBE+V10) and the deviation of the V10 is obtained. A current to flow to the emitter of the transistor 4 is turned to a value subtracting a current value I4 of a fourth constant current source 9 from a current value I3 of the third constant current source 8. This value is DELTAI=I3-I4. By making a value I2 of a second constant current source 7 and this value DELTAI almost equal, the emitter current of the fourth transistor 4 and the emitter current of the third transistor 3 are made almost equal as well, and the base currents of both of transistors, namely, the bias currents of the OP amplifiers are made almost equal.
