Rebel, a multi-process welding system
ESAB introduced the Rebel EMP 215ic, a 120V-230V, CC/CV welding system that offers true multi-process arc performance, location flexibility, lightweight portability and a groundbreaking operator interface. A unique sMIG (“smart MIG”) function enables users to begin MIG welding – with an extremely stable arc – just by setting metal thickness and wire diameter. Unlike competitive units, there is no need to enter information ...
Stretchable circuits could yield next-gen wearables
The consumer marketplace is flooded with a lively assortment of smart wearable electronics that do everything from monitor vital signs, fitness or sun exposure to play music, charge other electronics or even purify the air around you - all wirelessly. Now, a team of University of Wisconsin-Madison engineers has created the world's fastest stretchable, wearable integrated circuits, an advance that could drive the IoT and a much more connected, hig...
Organic nanowire synaptic transistors emulate biological synapses
A team of researchers with the Pohang University of Science and Technology in Korea has created organic nanowire synaptic transistors that emulate the working principles of biological synapses. As they describe in their paper published in the journal Science Advances, the artificial synapses they have created use much smaller amounts of power than other devices developed thus far and rival that of their biological counterparts.
Study on molecular doping yields better semiconductor designs
An understanding of why tungsten-doped thin films degrade so rapidly in air may lead to better designs for semiconductor technologies. A combination of experiments and theory have helped researchers at King Abdullah University of Science and Technology (KAUST) to improve the understanding of fundamental physics questions about molecular doping—these will underpin the development of organic solar cells and field effect transistors.
3-phase motor drive provides 100k rad total dose protection
Featuring 100k rad total dose protection and advanced circuit and logic protection to ensure fail-safe operation, Data Device Corporation (DDC) has announced a high-reliability, 3-phase radiation tolerant motor drive. The PW-82336 utilises a high-efficiency, radiation tolerant MOSFET output stage with 100VDC rating to deliver 5A continuous current (10A peak current) to the motor, along with flexible I/O, enabling a common design to be used across...
GaN RF power transistors suit cellular base stations
NXP Semiconductors has announced an expansion to its portfolio of 48V GaN RF power transistors optimised for Doherty power amplifiers for use in current and next-gen cellular base stations. The four new transistors collectively cover cellular bands from 1,805 to 3,600MHz, meeting the needs of wireless carriers for superior performance at higher frequencies.
1,400W RF transistor withstands extreme load mismatches
A 1,400W, CW capable, high power extremely rugged transistor has been introduced by Ampleon. Constructed in a thermally optimised air cavity ACP3 copper flanged plastic package, the BLCU188XRS is able to withstand load mismatches up to a VSWR > 65:1.This Gen6 HV 50V LDMOS device has a 30% better thermal resistance compared to a traditional air cavity ceramic packaged transistor and, combined with its high efficiency, requires less stringent co...
Reduce semiconductor process development time
Synopsys has announced a pre-wafer simulation solution to help semiconductor manufacturers reduce process node development time. The solution provides a comprehensive process, transistor and circuit simulation flow that enables technology development and design teams to evaluate various transistor and process options using a design technology co-optimisation methodology that starts in the pre-wafer research phase.
Biosensor chip can detect DNA mutations
Bioengineers at the University of California, San Diego have developed an electrical graphene chip capable of detecting mutations in DNA. Researchers say the technology could one day be used in various medical applications such as blood-based tests for early cancer screening, monitoring disease biomarkers and real-time detection of viral and microbial sequences. The advance was published inProceedings of the National Academy of Sciences.
A world record in wireless data transmission
Transmitting the contents of a conventional DVD in under ten seconds by radio transmission is incredibly fast – and a new world record in wireless data transmission. With a data rate of 6 Gb per second over a distance of 37 km, a collaborative project with the participation of researchers from the University of Stuttgart and the Fraunhofer Institute for Applied Solid State Physics IAF exceeded the state of the art by a factor of 10.
