CHAOS-BASED MIXED SIGNAL IMPLEMENTATION OF SPIKING NEURONS

A new design of Spiking Neural Networks is proposed and fabricated using a 0.35 mu m CMOS technology. The architecture is based on the use of both digital and analog circuitry. The digital circuitry is dedicated to the inter-neuron communication while the analog part implements the internal non-linear behavior associated to spiking neurons. The main advantages of the proposed system are the small area of integration with respect to digital solutions, its implementation using a standard CMOS process only and the reliability of the inter-neuron communication.
