In this work, I present a CMOS implementation of a neuromorphic system that aims to mimic the behavior of biological neurons and synapses in the human brain. The synapse is modeled with a memristor-resistor voltage divider, while the neuron-emulating circuit (“CMOS Neuron”) comprises transistors and capacitors. The input aggregation and output firing characteristics of a CMOS Neuron are based on observations from studies in neuroscience, and achieved using both analog and digital circuit design principles. The important Spike Timing Dependent Plasticity (STDP) learning scheme is explored in detail, and a simple adaptive learning experiment is performed to demonstrate the CMOS Neuron’s potential for future artificial intelligence applications.
