- 9 - Abstract of the Disclosure A current mirror circuit in which error between input current and output current is small and which can operate with low voltage. First and second current mirror transistors of a first conductivity type have their emitters each connected to a power supply, their bases connected together and their collectors connected to an input terminal and an output terminal respec- tively. A current amplification factor compensating third transistor of the first conductivity type is provided which has its emitter connected to the bases of the first and second transistors and its collector connected to a reference potential point. A fourth transistor of a second conductivity type is provided for level shifting. This transistor has its collector connected to the emitters of the first and second transistors, its emitter connected to the base of the third transistor and its base connected to the collector of the first transistor. A current source is connected between the third transistor and the reference potential point.
