利用二氧化钒的记忆特性，我们实验地演示了一种通过在LC轮廓中放置记忆电阻来实现自适应滤波的方法。该电路对选择频率信号的施加作出反应，使其谐振响应的品质因数锐化，从而根据输入波形进行“学习”。该电路仅使用模拟无源元件，可应用于仿生处理和信息存储。我们还从数学上扩展了学习电路框架，以包括记忆反应元件，如记忆电容和记忆电感，并展示了这如何扩展自适应记忆过滤器的功能。(C)2010年美国物理研究所。[DOI：10.1063/1.3485060]
Using the memristive properties of vanadium dioxide, we experimentally demonstrate an adaptive filter by placing a memristor into an LC contour. This circuit reacts to the application of select frequency signals by sharpening the quality factor of its resonant response, and thus "learns" according to the input waveform. The proposed circuit employs only analog passive elements, and may find applications in biologically inspired processing and information storage. We also extend the learning-circuit framework mathematically to include memory-reactive elements, such as memcapacitors and meminductors, and show how this expands the functionality of adaptive memory filters.
