Researchers from Hiroshima University developed a high-speed transceiver that can receive or send data at a speed of 80 gigabits per second
A team of researchers from Hiroshima University, National Institute of Information and Communications Technology, and Panasonic Corporation developed a high-speed terahertz (THz) transceiver. The device can send or receive digital data at 80 gigabits per second (Gbit/s). The technology will be presented at the International Solid-State Circuits Conference (ISSCC) 2019 to be held from February 17 to February 21 in San Francisco, California, U.S. The team used silicon metalâ€“oxideâ€“semiconductor (CMOS) integrated circuit technology to develop the transceiver.
THz band offers a new and vast frequency and can be used for ultrahigh-speed wireless communication services. The single-chip transceiver can receive or transfer data at a speed of 80 Gbit/s with the help of channel 66 defined by the Institute of Electrical and Electronics Engineersâ€™ (IEEE) Standard. According to the standard, lower THz frequency range between 252 gigahertz (GHz) and 325 GHz is considered as a high-speed wireless communication channel.
In 2017, the team developed a band transmitter chip with a strength of 300-GHz and a receiver chip with 32 Gbit/s capability. The chip can achieve a speed of 105 Gbit/s. The current approach deals with the combination of a transmitter and a receiver into a single transceiver chip. Power combining as a technique can be used in transmitters to boost performance. However, the approach cannot be applied to receivers, which reduces the performance speed of the overall system unless an equally fast receiver is available.
The ability to achieve CMOS receiver performance close to 100 Gbit/s is a breakthrough in technological singularity. Research and innovation in computational power, communication speed, and capacity within and between computers is important. Such high-speed CMOS integrated circuit technology can be used in data transfer during space missions and can help to offer real-time data services over long distances, which can again prove vital in healthcare services.
