A Compact Four Transistor CMOS-Design of a Floating Memristor for Adaptive Spiking Neural Networks and Corresponding Self-X Sensor Electronics to Industry 4.0

In this work we present, in the context of the transition from amplitude to robust spike domain sensing and electronics, a floating memristor. It can be used to construct memristor SNNs used for noise-robust conditioning and analog-to-digital conversion and manufactured using leading-edge technologies with more ’cranky’ devices, low-voltage, low power, and minimal area on-chip. Also, this supports both machine learning as well as the self-x properties in advanced sensor electronics system for industry 4.0. The proposed memristor has less design complexity and a higher number of resistance levels as compared to other existing memristors. The proposed CMOS memristor is designed using AMS 0.35 μm CMOS technology and Cadence design tools. Its layout occupies an area of 70 μm × 85 μm. The simulation shows the performance of the proposed floating memristor emulator in the temperature range (-40 °C to 85 °C) and Monte-Carlo simulation.
