Ultra Low-Power Miniaturized Flexible Radio Optimized for Long-Term Battery Operation

Crossfield intends to develop a single chip software radio that is battery operated and can support high data rate wireless applications not currently addressed by off-the-shelf wireless standards such as IEEE802.15.4. By implementing a software radio, a single chip transceiver can interface to multiple transceiver “over the air” standards and can exploit new schemes as needed. The program will take maximum advantage of off-the-shelf CMOS RF designs implemented by Crossfield in 0.35 µm and 0.18 µm technologies. Certain mixed mode functions may be purchased or subcontracted to accelerate the schedule or to reduce overall program risk. All digital designs will be custom developed using a standard cell approach for the targeted process technology. Crossfield intends to complete the systems engineering and a significant part of the receiver RF design in Phase I. In Phase II, Crossfield will complete the transceiver design, fabricate and test a functioning device. The test device will be fabricated in the process technology defined at the beginning of Phase I.
