A Programmable Analog Device Based Emulation Circuit Design for Excitatory and Inhibitory Neurons

In the real neuronal systems, the sum of the inhibitory and the excitatory effects makes the neuronal firing easier or more difficult in the post-synaptic neurons. The dynamics of interaction between simple excitatory and inhibitory neuron populations can be mimicked by the Wilson-Cowan (WC) neuronal model. On the other hand, recently, the hardware realization of the neuronal systems takes to attentions in the bio-inspired system based studies. The common outcomes of these studies are focused on the low power, the low area, the less element consumption, the sensitive parameter setting and the programmability issues and programmable analog/digital devices contains several of these features. In line of this motivation, the FPAA based realization of the W-C neuronal model, has been achieved, successfully in this study.
