Realização de chaves RF baseadas na tecnologia Memristor.

Abstract

One of the inconveniences of the RFID (Radio Frequency IDentification) chipless is the impossibility to reconfigure the data. The objective of this internship is to study low cost reconfigurable devices that can be used in RF applications. These devices are CBRAM (Conductive Bridging Random-Access Memory) based on the memristor technology. It was used copper and aluminum as electrodes and polymer as dielectric between them. The substrate used is the RO4003C. The Set and Reset voltages obtained are around -0,5 V to +1 V, respectively, after forming. The ratio between the Set and Reset resistances is 20 000. The bandwidth of the devices is about 2 GHz. In addition, problems were found with the roughness of the substrate, the diffusion of copper into the polymer and the geometry of the devices.
