[Abstract]:Nowadays, artificial neural network (Ann) has always been a major concern of many researchers, but its development is mostly based on the principles and rules of neural information calculus. A neural computational model with the structural characteristics and functions of the biological nervous system was constructed on the von Neumann computer. But the ultimate goal of the development of artificial neural networks is to study and understand the intelligent principles and behaviors of the biological nervous system at the nerve cell level, so as to construct intelligent machines with intelligent behavior in the way of the biological nervous system. This is essentially different from the Von Neumann system computer, which can be defined as the fifth generation intelligent computer. The most important problem in the implementation of artificial neural networks at the hardware level is to solve the integration and connectivity of neuronal circuits and synaptic circuits. With the development of new components in recent years, the appearance of nanometer components has brought a new breakthrough. The appearance of nanocrystalline silicon thin film transistor (Nc-Si TFT) which is smaller than the traditional CMOS can improve the reaction speed and reduce the power consumption. As an important part of neuron connection, synaptic circuit not only bears the function of transmission of information between neurons, but also has the ability to be molded to realize the memory and learning of the nervous system. The appearance of the resistor provides the basis for this. The resistor is a resistor with dynamic characteristics, the resistance value can depend on the excitation voltage to change, at the same time, it has the characteristics of low energy consumption, nanometer level, long memory, etc. It can be used as the basic part of the synaptic circuit to store the synaptic connection strength. In this paper, the background of the research is introduced, the development and application of the resistor are introduced in detail, and the simulation and performance analysis of the HP type resistor under the SPICE environment is carried out. Then, the development of artificial neural network and the associative learning algorithm which has important influence on the development of artificial neural network are introduced. Finally, the process of nano-scale TFT SPICE model is given in detail, and the performance simulation in electrical environment is carried out. On this basis, in order to realize the learning function of the memory device synaptic circuit, a "integration-excitation" type neuron SPICE simulation circuit is established. The working characteristics of each component in the circuit are analyzed, and the original Mead neuron circuit structure is improved. The pulse signal generation process of the circuit is simulated by SPICE. At the same time, combining the characteristics of TFT and amnesia, a new type of synaptic circuit structure for HEBB learning is proposed, which makes the synaptic circuit more consistent with the real biological synaptic characteristics, and improves the control flexibility and extensibility of the synaptic circuit. On the basis of this design, the learning rules based on monopulse HEBB learning and average excitation rate between two neural networks are realized. Furthermore, the Pavlov experiment based on neural network with multiple neurons is carried out, which proves the usability of the neural structure design in associative learning. At the same time, in order to prove that the circuit can provide the same function as the traditional logic gate circuit, the simulation experiment is carried out to detect the coincidence of input signal on the basis of self-learning. Realizing the basic functions of traditional circuits is an important basis for the development of neural computing intelligent computer.
