摘要

本文详细介绍了一种完全可编程的浮动忆阻器仿真器ASIC，该仿真器专为生物启发的忆阻学习而设计。由于真正的忆阻器尚未商品化，因此需要一个紧凑的忆阻器仿真器来进行器件研究。所设计的ASIC具有电导范围为4.88nS ~ 4.99μS (200KΩ ~ 204.8MΩ)的忆阻器仿真器。忆阻器仿真器是一种基于开关电阻的电路，其处理在FPGA中进行。处理已被计划在片外，以获得任何功能的可编程性的自由。本文介绍了忆阻器仿真器及其在长时程增强(LTP)、长时程抑制(LTD)和突触可塑性等神经形态回路中突触功能的实现。ASIC采用ams350nm工艺设计和制造。

Programmable memristor emulator ASIC for biologically inspired memristive learning

This paper details a fully programmable floating memristor (resistor with memory) emulator ASIC designed for biologically inspired memristive learning. Since real memristor is not commercially available, a compact memristor emulator is needed for device study. The designed ASIC has a memristor emulator with conductance range from 4.88nS to 4.99μS (200KΩ to 204.8MΩ). The memristor emulator is a switched-resistor based circuit with processing performed off-chip in a FPGA. The processing has been planned to be off-chip to get the freedom of programmability of any function. This paper explains the memristor emulator and the realization of synapse functionality used in neuromorphic circuits like long term potentiation (LTP), Long Term depression (LTD) and synaptic plasticity. The ASIC has been designed and fabricated in AMS 350nm process.
