Fujitsu Develops World’s first RF Transceiver Chip produced with 90 nm CMOS process technology

Fujitsu today announced the development of the world’s first radio frequency (RF) transceiver chip produced with 90 nm CMOS process technology that operates at the 77 gigahertz (77GHz) frequency, designed for use in automotive radars. The new transceiver chip includes several novel miniaturization technologies from Fujitsu Laboratories, including circuit design that employs inductor elements and a newly developed signal-distribution circuit that utilizes magnetic field coupling.

With a die size of 1.2 mm x 2.4 mm, this is the smallest example of a CMOS-based transceiver for the millimeter-band RF that has been reported thus far at an academic conference. Details of this technology were presented at the IEEE International Solid-State Circuits Conference 2009 (ISSCC 2009), held in San Francisco from February 8 to February 12.
