Leti, innovation
for industry
CEA-Leti and Nokia Research Center (NRC) have developed an RF front-end circuit that allows very high data rate content exchange between a reader – typically a mobile phone – and a memory tag. This circuit is currently used in the Nokia Explore and Share research prototype.
The circuit exhibits 112 Mb/s data-rate, a dramatic improvement over traditional Radio-frequency identification (RFID) systems.
The communication system merges two radio techniques: impulse Ultra-Wide Band (UWB), used for data transfer, and narrow-band Ultra high frequency (UHF) signal, used for synchronization and remote powering.
The same circuit is able to manage physical layer communication at both ends of the communication link, i.e. the same front-end can be used either in the memory tag or in the reader. Moreover, the circuit may power itself from the narrow-band signal and provide power for an external non-volatile memory device. The circuit also includes a battery-powered mode to increase the reading distance.
CEA-Leti and NRC will deliver a presentation on the circuit at the 2010 Symposium on Very-large-scale integration (VLSI) Technology and Circuits. The 2010 VLSI Symposium will be held on June 15-18, 2010 in Honolulu, Hawaii, USA.
