ABSTRACT:
A stabilized current sources network comprises nmultiple collector transistors each having m collectors connected to respective electronic elements, one of m collectors of any one of the transistors being coupled to a load resistor. The latter is coupled to a first common bus. There is a stabilization unit comprising a reference voltage source, an amplifier, and a comparison unit. The comparison unit has its first input coupled to the output of the reference voltage source, and has its second input coupled to the load resistor. The output of the comparison unit is coupled to the input of the amplifier whose output is coupled to the bases of the n multiple collector transistors having their emitters connected to a second common bus. The network makes it possible to decrease the number of components and insulated regions in LSI circuits and to enhance the stability of the associated current sources.
