ABSTRACT:
A current mirror circuit capable of accurately setting the ratio between input current and output current. The circuit includes a plurality of input terminals and a plurality of output terminals. A plurality of transistor pairs is provided with the first transistor of each pair having its collector connected to an input terminal. In addition, the collector of each first transistor in each pair is coupled to its own base. The bases of the transistors in each pair are coupled together, while the collector of the second transistor in each pair is coupled to an output terminal. The transistors connected to input terminals have their emitters coupled together and grounded through a first resistor. The transistors coupled to output terminals have their emitters coupled together and are grounded through a second resistor. Such a circuit allows ratios between input and output current to be set very accurately.
