Design Issues and Challenges of Memristor Structured Gas Receptive System

Memristors provide an efficient and reliable scope in the application of gas sensors. In recent years, technologies have progressed rapidly in meeting the demand for high density and low power semiconductors through innovative ideas on MOSFET, FINFET, memristors, etc. Hence, memristors provide a more reliable device for building a gas sensor. This paper mainly demonstrates on crossbar arrangement of memristors that can be used for sensing purposes to solve the integral problem of density and power. This work comprises a proposed flow chart for a gas sensing system that provides easy coding on a Verilog-A or SPICE module integrated with memristive characteristics. The crossbar arrangements with different existing array structures are elaborated. Comparative analysis of the previously proposed structures with their merits and demerits are presented.
