论文摘要
在本文中，我们提出了一个动态方案，以获取可重构噪声辅助逻辑门，该逻辑门可产生所有六个基本的2输入逻辑操作，包括XOR操作。该设置由两个在有噪声层的情况下由一个子阈值逻辑输入信号驱动的两个耦合双重子系统。其输出的同步状态，在最佳的噪声和耦合强度的最佳窗口中，将其稳健映射到驾驶信号的2输入逻辑操作。因此，噪声，非线性和耦合的相互作用导致嵌入在耦合系统的集体状态中的逻辑操作的出现。使用数值模拟和原始电路实验证明了这一想法。参数空间中产生可靠逻辑操作的区域是通过使用数值和实验数据的严格衡量可靠性来表征的。
In this article, we present a dynamical scheme to obtain a reconfigurable noise-aided logic gate, that yields all six fundamental 2-input logic operations, including the XOR operation. The setup consists of two coupled bistable subsystems that are each driven by one subthreshold logic input signal, in the presence of a noise floor. The synchronization state of their outputs, robustly maps to 2-input logic operations of the driving signals, in an optimal window of noise and coupling strengths. Thus the interplay of noise, nonlinearity and coupling, leads to the emergence of logic operations embedded within the collective state of the coupled system. This idea is manifested using both numerical simulations and proof-of-principle circuit experiments. The regions in parameter space that yield reliable logic operations were characterized through a stringent measure of reliability, using both numerical and experimental data.
