Circuit Design Based on Memristor to Realize LIF Neuron Function

LIF neuron function is one of the important synaptic properties. In this paper, a memristor neuron circuit is built to realize the LIF function, and Multisim software is used to simulate it, which lays a foundation for large-scale neuromorphic computing. In this paper, an effective memristor model is established on the basis ofHP memristor, and its output characteristic curve is obtained; A bridge memristor circuit is designed based on the memristor model. The principle of LIF neuron transmitting signal is analyzed. A circuit based on the LIF neuron model and the memristor module is designed to realize the function of LIF neuron. The LIF characteristics of neurons were verified by Multisim simulation, and the responses of neurons under different excitation levels were simulated. The use of memristors to realize LIF neuronal function is a key part of further neuromorphic computing.
