【摘要】：電磁環(huán)境的復(fù)雜化、多變化,使得應(yīng)用于傳統(tǒng)電子系統(tǒng)的抗擾方式逐漸暴露出其不足之處。相比之下,生物的可靠性、抗擾性、自適應(yīng)和自修復(fù)等特性,卻能在復(fù)雜電磁環(huán)境中表現(xiàn)出明顯的優(yōu)勢�；陔姶欧律雷o(hù)理念,以及生物體在復(fù)雜電磁環(huán)境下的自適應(yīng)抗擾優(yōu)勢,引發(fā)了對復(fù)雜電磁環(huán)境下仿生防護(hù)新方法的探索。本文通過研究生物神經(jīng)元突觸的自適應(yīng)抗擾機(jī)理,建立仿生模型,利用憶阻器仿生電路模擬神經(jīng)元突觸的功能特性。主要工作如下:1、基于神經(jīng)元突觸生物特性的理論分析,分析利用憶阻器模擬神經(jīng)元突觸的可行性,為仿生電路的設(shè)計構(gòu)建提供理論依據(jù)。通過憶阻器和神經(jīng)元突觸特性的對比,發(fā)現(xiàn)憶阻器的傳輸特性與突觸小體的信號傳遞方式存在一定的相似性;同時還發(fā)現(xiàn)其傳遞的方向也存在差異:突觸信號傳導(dǎo)方向單一,而憶阻器則是雙向傳遞,其傳遞方向受到外加電壓的制約。2、基于憶阻器特性的分析和理解,完成憶阻器仿生電路模型的搭建,并進(jìn)行電路的仿真與分析。通過對憶阻器特性方程的分析,借助流水線思想將特性方程轉(zhuǎn)化為流水線結(jié)構(gòu)式。然后,分別利用普通模塊和DSP Builder模塊完成憶阻器仿生電路的搭建,并進(jìn)行了仿真分析,所得結(jié)果與惠普實驗室實驗測得的結(jié)果基本一致。3、在FPGA仿真平臺中完成憶阻器仿生電路的設(shè)計與模擬分析。本文分別從仿真和驗證兩個方面進(jìn)行了分析:在QuartusⅡ的仿真分析中,通過RTL閱讀器設(shè)計了憶阻器仿生電路的總體框架和結(jié)構(gòu)詳圖,從內(nèi)部原理上描述了仿生電路的功能特點;在Modelsim驗證過程中,通過電路輸出波形證明了仿生電路的正確性。
[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，
