A relatively small value of current is obtained in an integrated circuit by separating a larger current into two or more parts. The circuit includes two transistors and at least two strings of the same number of series connected diodes. Currents in a fixed ratio to one another are applied in the forward direction to the two strings of diodes and the voltages thereby obtained are applied to the respective base electrodes of the transistors. The larger current is applied in parallel to the emitter-to-collector paths of the two transistors and that part of this current which passes through the one of the transistors drawing the smaller of the two currents, is the current of interest. |
