Abstract

The present invention provides an analog current distributor for current regulation, which specifically includes two improved CCCII circuits, namely a first CCCII circuit and a second CCCII circuit, and the voltage signal ports X of the first CCCII circuit and the second CCCII circuit are both connected to Reference voltage V REF , the current signal port Y and the current signal port Z of the first CCCII circuit and the second CCCII circuit are both connected to the reference current I REF , the analog current divider can also include a plurality of improved CCCⅡ circuits to realize multiple outputs. The sum of the output current of the analog current divider proposed by the present invention is equal to the input reference current, and the ratio of the output current can be referenced by other inputs. The current proportional control can control a more precise output current and can be used for more precise current signal (below uA level) processing.

Description

technical field [0001] The invention relates to the field of analog integrated circuits, in particular to an analog current distributor for current regulation. Background technique [0002] A current divider is an analog integrated circuit that can convert one current signal into two or more current signals. Because its output current signal can be fine-tuned, it is a common module for control, instrumentation and communication systems. Compared with the voltage divider, the current distribution circuit has the advantages of large bandwidth, high precision, low power consumption, good linearity, simple circuit and wide dynamic range, and has been widely used. The current signals output by the existing analog current dividers are mainly microamps (uA) level and above, which cannot be applied to process more precise current signals (below uA level). Therefore, there is an urgent need for a more precise current signal processing. The new type of current distributor. SUMMARY ...
