【摘要】：忆阻器是蔡少棠教授根据电路变量的对称性提出的理想元件,是联系电荷和磁通的第四种元器件。忆阻器可算是电子技术领域上的一个里程碑式的发现。忆阻器的发现为电路设计及其相关应用提供了全新的思路和更大的发展空间,且有力地推动了电路理论新体系的建立和完善。忆阻器独特的记忆特性和纳米尺寸为电路设计和应用提供了更大的发展空间,在通信保密、人工智能、模拟神经元突出等发面有广泛的应用。滤波电路是一种对信号进行处理和加工的器件。随着电子市场的不断发展,得到广泛生产和实际应用。滤波电路的用途是从具有多种频率成分的信号中根据需求提取具有特定频率的信号,即允许某一频率范围的信号顺利通过,而抑制其余部分频率的信号,本质上是一种选频电路。滤波电路作为一种重要的电路元器件,已经广泛应用在信号处理、通信工程、测量勘察和自动控制系统中。随着工业技术和电子技术的不断提升和进步,在大规模集成电路和信号处理系统中对滤波电路的结构和性能方面提出更高的要求,要求滤波电路的结构精细、占用空间小,性能精度高、误差小。本文阐述了忆阻器的基本理论和三个本质特征。分析了 HPTi02线性杂质漂移模型、二次非线性忆阻器模型和三次非线性忆阻器模型,并提出了一种新的四次非线性忆阻器模型,通过仿真验证,该模型完全符合忆阻器的三个本质特征。并参考“浮地”二端口电路设计方法,设计了四次非线性忆阻器的“浮地”二端口电路。并设计了基于该模型的忆容器和忆感器,并对由该模型组成的复合忆阻电路进行了分析,包括忆阻器串联电路和并联电路。重点讨论将四阶非线性模型应用到四阶巴特沃斯低通、高通和带通滤波电路中,通过Multisim仿真验证,基于四阶非线性忆阻器模型的滤波电路和普通电阻元件组成的滤波电路性能接近,同时也证明了忆阻器应用于高阶滤波电路思路的正确性和可行性,为忆阻器应用于更高阶、更复杂的滤波电路提供借鉴。
[Abstract]:Amnesia is an ideal component proposed by Professor Tsai Shao-tong according to the symmetry of circuit variables. It is the fourth kind of component associated with charge and flux.The resistor can be regarded as a landmark discovery in the field of electronic technology.The discovery of the resistor provides a new way of thinking and more development space for the circuit design and its related applications, and promotes the establishment and perfection of the new circuit theory system.The unique memory characteristics and nanometer size of the resistor provide more development space for circuit design and application. It has been widely used in communication security, artificial intelligence, analog neuron protruding and so on.Filter circuit is a device for signal processing and processing.With the continuous development of the electronic market, it has been widely used in production and practice.The purpose of the filter circuit is to extract signals with specific frequencies from signals with multiple frequency components according to requirements, that is, to allow signals in a certain frequency range to pass smoothly and to suppress signals at the rest of the frequency.It is essentially a frequency-selective circuit.As an important circuit component, filter circuit has been widely used in signal processing, communication engineering, survey and automatic control system.With the continuous improvement and progress of industrial technology and electronic technology, the structure and performance of filter circuits in large-scale integrated circuits and signal processing systems are required to be higher, which requires the structure of filter circuits to be fine and occupy less space.The performance accuracy is high, the error is small.This paper describes the basic theory and three essential features of the resistor.The model fully accords with the three essential features of the resistor.Referring to the design method of "floating ground" two-port circuit, the "floating-ground" two-port circuit of fourth order nonlinear resistor is designed.The memory container and sensor based on the model are designed, and the compound circuit composed of the model is analyzed, including the series circuit and the parallel circuit.The application of fourth-order nonlinear model to fourth-order Butterworth low-pass, high-pass and band-pass filter circuits is discussed, and the simulation results of Multisim are given.More complex filter circuits provide a reference.
