Wireless Interfaces

See project descriptions


The Wireless Interfaces Thrust undertakes basic and applied research in wireless interfaces for environmental and biomedical sensor devices. The Thrust is exploring CMOS and RF MEMS circuits, miniature antennas, and sensor networking. Full systems incorporating these components are being developed and demonstrated. The Wireless Interfaces Thrust is developing wireless interfaces to neural probes, cochlear implants, and other biomedical devices such as arterial stent monitors. The Thrust is exploring techniques for moderate range, moderate rate, wireless communication to environmental sensors. Key goals are power efficiency and small size. Wireless circuits and systems based on RF MEMS and nanometer CMOS are being researched. The demonstration of low-power CMOS transceivers for the 802.15.4 2.4GHz sensor network standard is a medium-term goal. Other applications and approaches including RFID and low-power, super-regenerative receivers are also being considered. New techniques that significantly improve the performance and energy efficiency of analog-to-digital converters are being explored. The Wireless Interface Thrust is also researching circuit and process techniques that will permit the integration of RF MEMS and CMOS wireless circuits. A long-term goal is the integration of RF MEMS, power-efficient CMOS RF, and CMOS baseband circuitry, as well as digital signal processing and miniature antennas in a signal package.
