Sensing with Memristive Complementary Resistive Switch: Modelling and Simulations

Abstract

Sensors give factual and process information about the environment or other physical phenomena. Sensing using memristors has been recently introduced for its potential for high density integration and miniaturization. Complementary Resistive Switch (CRS) based sensor provides an extremely efficient crossbar array that reduces the sneak current. The objective of this paper is to introduce and evaluate a circuit model for sensing using memristive complementary resistive switch. We introduce a reliable SPICE implementation of memristor model that captures the sensing behaviour of memristor. Our simulation results also validate the SPICE model for CRS sensing architecture, whose parameters could be easily adapted to match experimental data. The results also investigate the sensitivity and device behaviour of memristor and CRS sensor device in the presence of oxidizing and reducing gases of different concentration.
