چکیده

A neural synapse circuit design is presented here. The circuit models the result of an action potential applied to a biological synapse, including neurotransmitter action, membrane potentials, and ion pumps. The output of the circuit is an Excitatory PostSynaptic Potential (EPSP). The circuit is simulated using carbon nanotube SPICE models.

Implementation of a programmable neuron in CNTFET technology for low-power neural networks

Circuit-level implementation of a novel neuron has been discussed in this article. A low-power Activation Function (AF) circuit is introduced in this paper, which is then combined with a highly linear synapse circuit to form the neuron architecture. Designed in Carbon Nanotube Field-Effect Transistor (CNTFET) technology, the proposed structure consumes low power, which makes it suitable for the...

Function Learning with Carbon Nanotube-based Synapses

The principle of using nanoscale memory devices as artificial synapses in neuromorphic circuits is recognized as a promising way to build new circuit architectures tolerant to defects and variability. Yet, actual experimental demonstrations of neural network type of circuits based on non-conventional/nonCMOS memory devices and displaying function learning capabilities remain very scarce. We rec...

Theoretical Study on the Chemical Reactivity in the Armchair Single-walled Carbon Nanotube: Proton and Methyl Group Transfer

Proton transfer (PT) and methyl group transfer (MGT) occurring in small biomimetic systems, Formamide-Formamidic acid (FA-FI), and N-formyl-N-methylformamide-(E)-methyl N-formylformimidate (NMFA-NMFI) are investigated in the gas phase and in single-walled carbon nanotubes by using the density functional theory and the ONIOM approach. It is shown that PT reaction is disfavoured in single-walled ...

Semiconductor Nanorod–Carbon Nanotube Biomimetic Films for Wire-Free Photostimulation of Blind Retinas

We report the development of a semiconductor nanorod-carbon nanotube based platform for wire-free, light induced retina stimulation. A plasma polymerized acrylic acid midlayer was used to achieve covalent conjugation of semiconductor nanorods directly onto neuro-adhesive, three-dimensional carbon nanotube surfaces. Photocurrent, photovoltage, and fluorescence lifetime measurements validate effi...
