Abstract

Abstract RRAM devices have recently seen wide-spread adoption into applications such as neural networks and storage elements since their inherent non-volatility and multi-bit-capability renders them a possible candidate for mitigating the von-Neumann bottleneck. Researchers often face difficulties when developing edge devices, since dealing with sensors detecting parameters such as humidity or temperature often requires large and power-consuming ADCs. We propose a possible mitigation, namely using a RRAM device in combination with a comparator circuit to form a basic block for threshold detection. This can be expanded towards programmable non-uniform sampling ADCs, significantly reducing both area and power consumption since significantly smaller bit-resolutions are required. We demonstrate how a comparator circuit designed in 130 nm technology can be reprogrammed by programming the incorporated RRAM device. Our proposed building block consumes 83 µW.
用于可编程非均匀采样ADC的基于RRAM的构建块
摘要RRAM器件最近被广泛应用于神经网络和存储元件等应用中,因为其固有的非易失性和多位能力使其成为缓解冯·诺依曼瓶颈的可能候选者。研究人员在开发边缘设备时经常面临困难,因为处理检测湿度或温度等参数的传感器通常需要大型功耗ADC。我们提出了一种可能的缓解措施,即使用RRAM器件与比较器电路相结合来形成阈值检测的基本块。这可以扩展到可编程的非均匀采样ADC,显著减少面积和功耗,因为需要显著更小的比特分辨率。我们展示了在130中如何设计比较器电路 nm技术可以通过对所结合的RRAM器件进行编程来重新编程。我们提出的构建块消耗83 µW。
