In this paper, new active-only memristor emulator circuits based on only one active element and one single transistor are proposed. These circuits use intrinsic capacitors of the MOS transistors without using any external passive components. These types of circuits have some important advantages over the integrated circuit, such as low occupied chip area and electronic tuning capability. However, memristor emulator circuits suffer from limited operation frequency range. To address this issue, a new modification technique used to extend circuits’ operating frequency range is introduced. Furthermore, the proposed memristor emulators can also be used to implement basic filtering functions. The main nonidealities are studied and proper operations of these circuits are provided via Spectre Simulation results in 0.18 μm Cadence design tool.

本文提出了一种仅基于一个有源元件和一个单个晶体管的新型仅有源忆阻器仿真器电路。这些电路使用MOS晶体管的本征电容器，而无需使用任何外部无源组件。这些类型的电路相对于集成电路具有一些重要的优势，例如占用的芯片面积小和电子调谐能力强。但是，忆阻器仿真器电路的工作频率范围有限。为了解决这个问题，引入了一种新的修改技术，用于扩展电路的工作频率范围。此外，所提出的忆阻器仿真器还可用于实现基本的滤波功能。研究了主要的非理想性，并通过0.18μmCadence设计工具中的Spectre Simulation结果提供了这些电路的正确操作。
