    • 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.
    • 稳定电流源网络包括多个集电极晶体管,每个集电极晶体管具有连接到相应电子元件的m个集电极,其中一个晶体管的一个集电极耦合到负载电阻器。 后者耦合到第一公共总线。 存在包括参考电压源,放大器和比较单元的稳定单元。 比较单元具有耦合到参考电压源的输出的第一输入,并且其第二输入耦合到负载电阻器。 比较单元的输出耦合到放大器的输入端,放大器的输出耦合到其多个发射极连接到第二公共总线的n个多个集电极晶体管的基极。 该网络可以减少LSI电路中的元件数量和绝缘区域,并增强相关电流源的稳定性。
