Patent ID: 7113005

Claim:
A current mirror circuit for inputting input current to an input terminal and outputting output current to an output terminal, comprising: input side and output side bi-polar transistors of which bases are commonly connected; an input side MOS transistor of which source is connected to a collector of the input side bi-polar transistor and of which drain and gate are connected to the input terminal; an output side MOS transistor of which source is connected to a collector of the output side bi-polar transistor, of which drain is connected to the output terminal, and of which gate is set to a potential substantially the same as the gate of the input side MOS transistor; and an MOS transistor for supplying base current, of which source is connected to the bases of the input side and output side bi-polar transistors, and of which gate is connected to the gate of the input side MOS transistor.
