Résumé : This Master’s thesis describes the design of an artificial biological neuron system in CMOS circuit 180 nm technology to replace a dead neuron between two active neurons and thus restore communication in paralyzed individuals. The main goal of this work is to design a spiking leaky Integrator and Fire (LIF) neuron with refractory period mechanisms, which achieve a low power consumption; an adaptive homeostatic synapse with short and long-term spike plasticity, that reconfigure the spiking neuron networks of multichannel sensor electrodes to record the electric signal from the active cell; a low-power common source current reuse regulated cascode CS-CR-RGC TIA circuit with a high transimpedance gain for faithful amplification and ultra-low-noise for high sensitivity. The scheme occupies a small active area of 89 µm x 67 µm.
