基于忆阻器的基本算术运算电路
Memristor-based Circuits for Performing Basic Arithmetic Operations
摘要：
在几乎所有当前工作的电路中，特别是在实现信号处理应用的模拟电路中，对由电压或电流表示的值执行诸如乘、加、减和除的基本算术运算。然而，在本文中，我们提出了一种新的和简单的方法来执行模拟算术运算，在这个方案中，信号表示和存储通过新发现的电路元件，即忆阻器的忆阻，而不是电压或电流。其中一些运算器，如除法器和乘法器，比它们的等效电压基电路简单得多，速度也快得多，而且它们需要更少的芯片面积。此外，设计了一种新的电路，用于用预定的模拟值编程忆阻器的忆阻。仿真结果验证了该电路的有效性和准确性。
英文摘要：
In almost all of the currently working circuits, especially in analog circuits implementing signal processing applications, basic arithmetic operations such as multiplication, addition, subtraction and division are performed on values which are represented by voltages or currents. However, in this paper, we propose a new and simple method for performing analog arithmetic operations which in this scheme, signals are represented and stored through a memristance of the newly found circuit element, i.e. memristor, instead of voltage or current. Some of these operators such as divider and multiplier are much simpler and faster than their equivalent voltage-based circuits and they require less chip area. In addition, a new circuit is designed for programming the memristance of the memristor with predetermined analog value. Presented simulation results demonstrate the effectiveness and the accuracy of the proposed circuits.
