摘要:

我们报告的混合信号6抽头有限脉冲响应(FIR)滤波器的实验演示,其中的权重与二氧化钛忆阻器件实现。在所提出的设计中,抽头的权重以相对高的精度存储在可以现场配置的忆阻器件中。这种方法使得能够在模拟域中有效地实现FIR滤波器的最关键的操作,即输入信号与抽头权重的相乘以及来自抽头的乘积的求和。因此,所提出的设计,当实现与完全集成的混合CMOS/忆阻器电路,预计将更加紧凑和节能的最先进的方法相比。

英文摘要:

We report on experimental demonstration of a mixed-signal 6-tap finite-impulse response (FIR) filter in which weights are implemented with titanium dioxide memristive devices. In the proposed design weight of a tap is stored with a relatively high precision in a memristive device that can be configured in field. Such approach enables efficient implementation of the most critical operation of an FIR filter, i.e. multiplication of the input signal with the tap weights and summation of the products from taps, in analog domain. As a result, the proposed design, when implemented with fully integrated hybrid CMOS/memristor circuit, is expected to be much more compact and energy efficient as compared to the state-of-the-art approaches.
