ABSTRACT:
A current source circuit has a current division circuit and a correction circuit. The current division circuit has a current source and a plurality of current shunting transistors series-connected between "+" potential and "-" potential. Each stage of current shunting transistors has at least one current output transistor. The emitters of the transistors of each stage are commonly connected, and bases thereof are also commonly connected. The bases of the transistors of each stage are supplied with predetermined voltages. The output currents are obtained from current output transistors of each stage. The correction circuit consists of a plurality of correction stages arranged in correspondence with the plurality of stages of the current division circuit.
