Filed: 1984-05-11
Abstract: PURPOSE:To obtain a constant current having a desired temperature characteristic, by connecting transistors, between emitter of which a resistance is connected, with a pair of transistors constituting a current mirror circuit and controlling an output transistor. CONSTITUTION:When collector current of transistors Q3 and Q4 becomes equal to each other, a circuit is balanced and stabilized and the collector current of a transistor Q5 becomes equal to the collector currents of the transistor Q3 and Q 4. The collector voltage of a transistor Q2 is impressed across the base of a transistor Q6 and a voltage corresponding to the base voltage is obtained at a load resistance R8. When the value of the resistance R8 is made equal to that of a resistance R7, the voltage produced in the resistance R8 becomes equal to the voltage produced across both ends of a resistance R5. Moreover, since the emitter currents of the transistor Q3 and Q4 are equal to each other, the voltage across both ends of the resistance R5 becomes 10XKT/qln10 and the voltage at the resistance R8 is proportional to absolute temperature T.
