Research Abstract

A chaotic neuron model has been implemented as an integrated circuit (IC) form using switched-capacitor circuit technique. The model includes a relative refractoriness and an analog output function of the axon hill-lock which are important characteristics of biological neurons. The integrated chaotic neuron circuit has current input nodes in order to add many input currents easily. A current to voltage converter circuit was specially designed for this purpose.
Furthermore, a synaptic circuit has been integrated as an IC form in order to construct a large scale chaotic neural network by connecting many neuron circuits. Within the synaptic chip, many current-mode synapse circuits and analog memories for synaptic weights are integrated. The analog memories are periodically refreshed by a master current copier circuit.
By using the above neuron chips and synaptic chips, a small-scale but full-functional chaotic neural network has been constructed. The network characteristics have been tested using the following three basic problems ;
1.Dynamical Associative Memory : From experiments, a dynamical retrieval of memories like animals do has been confirmed.
2.Optimization Problems : As an example, a traveling salesman problem has been solved using the network. As a result, very high solving ability of the network has been confirmed.
3.Synchronization of Chaos : synchronous motion of some chaos in the network has been achieved.
The behavior of the implemented chaotic neural network system can be observed in real-time. Therefore, it is possible to analyze the process of information processing of a coupled chaotic system from the view point of dynamics theory or information theory by constructing a larger network. The expansion of the size of the network and construction of a multi-order parallel observation system are future problems.
