Abstract：
The invention provides a simulation current distributor for current regulation and control, which specifically comprises two improved CCCII circuits, namely a first CCCII circuit and a second CCCII circuit, voltage signal ports X of the first CCCII circuit and the second CCCII circuit are both connected with a reference voltage VREF, a current signal port Y and a current signal port Z- of the first CCCII circuit and a current signal port Z- of the second CCCII circuit are both connected with a reference current IREF, the analog current distributor can further comprise a plurality of improved CCCII circuits so as to achieve multi-path output, the sum of the magnitude of the output current of the analog current distributor is equal to the input reference current, and the proportion of the output current can be regulated and controlled by other input reference current proportions, so that finer output current can be regulated and controlled, and the method can be used for processing finer current signals (below uA level).
