【摘要】：电磁环境的复杂化、多变化,使得应用于传统电子系统的抗扰方式逐渐暴露出其不足之处。相比之下,生物的可靠性、抗扰性、自适应和自修复等特性,却能在复杂电磁环境中表现出明显的优势。基于电磁仿生防护理念,以及生物体在复杂电磁环境下的自适应抗扰优势,引发了对复杂电磁环境下仿生防护新方法的探索。本文通过研究生物神经元突触的自适应抗扰机理,建立仿生模型,利用忆阻器仿生电路模拟神经元突触的功能特性。主要工作如下:1、基于神经元突触生物特性的理论分析,分析利用忆阻器模拟神经元突触的可行性,为仿生电路的设计构建提供理论依据。通过忆阻器和神经元突触特性的对比,发现忆阻器的传输特性与突触小体的信号传递方式存在一定的相似性;同时还发现其传递的方向也存在差异:突触信号传导方向单一,而忆阻器则是双向传递,其传递方向受到外加电压的制约。2、基于忆阻器特性的分析和理解,完成忆阻器仿生电路模型的搭建,并进行电路的仿真与分析。通过对忆阻器特性方程的分析,借助流水线思想将特性方程转化为流水线结构式。然后,分别利用普通模块和DSP Builder模块完成忆阻器仿生电路的搭建,并进行了仿真分析,所得结果与惠普实验室实验测得的结果基本一致。3、在FPGA仿真平台中完成忆阻器仿生电路的设计与模拟分析。本文分别从仿真和验证两个方面进行了分析:在QuartusⅡ的仿真分析中,通过RTL阅读器设计了忆阻器仿生电路的总体框架和结构详图,从内部原理上描述了仿生电路的功能特点;在Modelsim验证过程中,通过电路输出波形证明了仿生电路的正确性。
[Abstract]:Because of the complexity and variety of electromagnetic environment, the disturbance rejection mode used in traditional electronic systems has gradually exposed its shortcomings. In contrast, biological reliability, immunity, self-adaptation and self-repair can exhibit obvious advantages in complex electromagnetic environments. Based on the idea of electromagnetic bionic protection and the adaptive immunity advantage of organism in complex electromagnetic environment, the new bionic protection method in complex electromagnetic environment is explored. In this paper, a biomimetic model is established by studying the adaptive anti-disturbance mechanism of the synapses of biological neurons, and the functional characteristics of the synapses of neurons are simulated by means of the biomimetic circuit of the amnesizer. The main work is as follows: 1. Based on the theoretical analysis of the biological characteristics of neuronal synapses, the feasibility of simulating neuronal synapses with amnesia is analyzed, which provides a theoretical basis for the design and construction of bionic circuits. By comparing the characteristics of amnesia and neuronal synapse, it is found that the transmission characteristic of amnesia is similar to that of synaptosome, and the direction of transmission is also different: the direction of synaptic signal transduction is single. On the other hand, the device is bidirectional, and its transfer direction is restricted by the applied voltage. Based on the analysis and understanding of the characteristics of the resistor, the bionic circuit model of the device is built, and the circuit simulation and analysis are carried out. Through the analysis of the characteristic equation of the resistor, the characteristic equation is transformed into the pipeline structure by the pipeline thought. Then, the common module and DSP Builder module are used to build the bionic circuit of the resistive device, and the simulation analysis is carried out. The results obtained are basically consistent with those measured by HP laboratory experiments. The design and simulation analysis of the bionic circuit of the amnesia are completed in the FPGA simulation platform. In this paper, two aspects of simulation and verification are analyzed: in the simulation analysis of Quartus 鈪，
