LONDON Renesas Technology Corp. has started working with IMEC (Leuven, Belgium) to perform research on 45-nm RF transceivers targeting cognitive radios capable of sending and receiving data at gigabits per second.
Researchers from Renesas will reside at IMEC and Renesas has joined IMEC's software-defined radio (SDR) front-end program, which includes the development of reconfigurable RF ICs, analog-to-digital converters (ADCs) and approaches to digitizing future RF architectures.
In the near term, IMEC's SDR-front-end program targets the development
of a cost-, performance- and power-competitive reconfigurable radio implemented in 45-nm digital CMOS technology. This radio will have a programmable center frequency that is variable from 100-MHz to 6-GHz and
a programmable bandwidth from 100-kHz to 40-MHz. This should allow it to cover many communication standards, at a level of performance comparable with single-mode transceivers, IMEC said.
The research program builds on Scaldio, IMEC's 130-nm RF transceiver results (published at ISSCC 2007), evolutions of IMEC's ADCs published at ISSCC
"The ability to develop an innovative RF architecture with scaled-down CMOS technology and circuit technologies in transceiver products supporting next-generation cellular standards such as 3GPP-LTE and 4G is one of the key differentiators for our products that are superior in cost advantages, performance and power," said Masao Nakaya, board director and executive general manager of LSI product technology unit at Renesas, in a statement issued by IMEC. "We aim to contribute to the early realization of next-generation mobile phones by combining our advanced semiconductor solutions with IMEC's R&D expertise in RF technology."
