Korean Researchers Announce High-Speed, Low-Power RF Chip

Korea Advanced Institute of Science and Technology researchers have developed a low-power, 60-GHz RF chip that wirelessly transmits large amounts of data between devices. The integrated circuit reportedly can send data up to 10.7 Gbits per second. Bluetooth high speed technology, for comparison, has an average data transfer rate of 24 Mbps. Existing high-speed wireless chips require significant amounts of energy, which has delayed their development. The new chip uses as little as 67 mW of power: 31mW to send and 36mW to receive data. The compact device also has a single antenna and an integrated switch. The researchers say the chip can be installed on mobile devices or cameras.(EurekAlert)(Korea Advanced Institute of Science and Technology @ EurekAlert)(Korea Advanced Institute of Science and Technology @ YouTube)

New Chip Uses Various Power Sources

MIT researchers have developed a chip able to use different power sources simultaneously to optimize power delivery. The chip operates with solar power and also harvests power from thermal sources and vibrations through a single control circuit, which enables the chip to have a constant source of power. Each energy source would traditionally need its own circuit as each method produces a different amount of energy. The new chip switches rapidly between each power source. Any excess is stored in capacitors for eventual use. Rather than directing the power created to a storage device such as a battery or a supercapacitor, the sensors in this new system can be directly powered, making it more efficient, say researchers. The technology could be used in biomedical devices as well as remote and difficult to reach monitoring sensors. The work is scheduled for publication in IEEE Journal of Solid-State Circuits.
