Fujitsu Develops World's Fastest 3-Volt CMOS A/D Converter

San Francisco, February 4, 1998 -- Fujitsu researchers today announced the development of the world's fastest CMOS Analog / Digital Converter. The A/D Converter is being introduced at the annual IEEE International Solid-State Circuits Conference being held in San Francisco.

Developed in cooperation with Fujitsu VLSI and Fujitsu Microelectronics Limited, the 6-bit Analog / Digital (A/D) converter employs a 3V power supply and was fabricated using a Fujitsu's 0.35-micron complementary metal oxide semiconductor (CMOS) technology. The super fast CMOS A/D converter is expected be used to speed up the operations of computers and consumer electronics, such as networking equipment and disk drives.

Development of an improved IAZ (Interleaved Auto-Zero) technique and a new error correction algorithm have made it possible to achieve high-speed operation of 400MS (Mega Samples)/second, the world's fastest. Furthermore, with its novel error detection/correction function, the device improves the error rate by a factor of 10,000 compared with devices lacking error correction while also shortening the delay time caused by code conversion.

Fujitsu's prototype A/D converter adopts three-layer (one layer of polysilicon and two layers of aluminum) 0.35-micron CMOS technology and assumes operations with both analog and digital embedded LSI's on CMOS. The company anticipates that this technology will have applications in such fields as hard disk drive, DVD and LAN technologies, where A/D converters control system performance.

Fujitsu researchers will present a paper on this development at the IEEE International Solid-State Circuits Conference (ISSCC98), the foremost global forum for presentation of advancements in solid state circuits, being held in San Francisco February 5 to 7th.

Fujitsu is presenting a total of six papers at this year's ISSCC and Dr. Naoki Yokoyama, Director of the Quantum Electron Devices Laboratory, Basic Technology Group at Fujitsu Laboratories, will receive the 1998 IEEE Morris N. Liebmann Memorial Award for his contributions to the development of self-aligned refractory-gate gallium arsenide MESFET integrated circuits.

ISSCC98 is sponsored by the Institute of Electrical and Electronics Engineers (IEEE) Solid-State Circuits Society. Cosponsors are the IEEE San Francisco Section and Bay Area Council, and the University of Pennsylvania. URL: http://www.sscs.org/isscc/1998/ap/
