摘要:This chapter covers all aspects that have to be considered for building highly efficient passive RFID tags with special abilities. Within a concrete project we are currently implementing such a tag. Besides the mandatory RF frontend and digital baseband processing it incorporates functionalities for multistandard communication, localization and sensing. Ultra low-power techniques enable these circuits to be implemented in a single chip without any other power supply than the RF field. The possibility to produce such RFID tags in high volumes and at low costs is a main objective of our project. Manifold monitoring solutions would profit from maintenancefree and ubiquitous sensor-data acquisition with position information using cheap, disposable RFID tags.
