Abstract
The efforts in realizing ubiquitous integrated circuits for ambient intelligence networks increased over the past few years. In particular, the passive radio frequency identification (RFID) presents a key technology for unattended wireless networks. A typical state of the art passive RFID systemconsists of an interrogator/reader and several passive Transponders. The interrogator communicates with the transponders by a wireless peer-to-peer connection and is responsible for the power supply of the passive transponders. To achieve a higher reading range and to improve the operational reliability of passive RFID sensor tags, the design of integrated circuits with an ultra low-power consumption and novel concepts for high-efficiency energy scavenging are required.
