Analysis of CMOS synapse generating excitatory postsynaptic potential using DC control voltages

Biological Synapse is an important and critical part of neuron as it involves mechanisms which involve communication, computation and modification i n t he c omplex interconnect of nervous system. This initiates modeling of a spike based neuron model which are implemented based on different functions and applications it can be used. This paper describes inhibitory synapse of Biomimetic Real-Time Cortex Project which is designed and simulated using widely available micron CMOS technology using SPICE circuit simulator. The need of using analog CMOS technology for implementation arises due to its simplicity, compactness and similar voltage levels as in complex neuronal interconnect. In addition to that it has biomimetic behavior involving modeling different mechanism such as neurotransmitter release, reuptake mechanism and spread delay controlled using voltage gated devices using DC control voltages.
