Abstract
A current mirror circuit comprises a first current-to-voltage converter for inputting an input current, a second current-to-voltage converter, a first transistor, the collector or drain of which outputs an output current, and the emitter or source of which is connected to the second current-to-voltage converter, and a control unit for controlling a control electrode of the first transistor. The control unit refers a voltage current-to-voltage converted by the first and second current-to-voltage converters to control the first transistor so that currents flow from the control unit to the first and second current-to-voltage converters at a predetermined ratio.
