The device delivers a copy of the input current as output current. There is a constant factor between the input and output current, and this factor is independent of the output load. The simplest configuration consists of two transistors. Iin = Iout ( 1 + 2/beta), with beta >> 2, Iin is equal Iout. For higher precision, the parameters of the two transistors need to be properly matched (VBE, beta). Integrating the two transistors into a single package ensures close thermal coupling and identical behavior of the two bipolar transistors versus temperature.
