A Memristive Architecture for Process Variation Aware Gas Sensing and Logic Operations

摘要

We propose novel memristive gas sensor architectures that can significantly reduce process and parametric variations in a predictable manner, while improving accuracy and overall power consumption. The proposed architecture can also be configured to realize multifunction logic operations as well as Complementary Resistive Switch with low hardware overhead in the absence of gasses. Our results show that the proposed architecture is significantly immune to process and parametric effects compared to a single sensor and almost unaffected by wire resistance, while offering much higher accuracy and much lower power consumption compared to existing techniques.
