Redefining power conversion efficiency
In order to create new opportunities for power supply designers to achieve greater efficiency in low voltage power supplies for computers, telecom networks, industrial and consumer devices, STMicroelectronics has introduced its latest MDmesh DM2 N-channel Power MOSFET transistors.
Helping to reduce design time
A mixed signal low power flow from Cadence Design Systems has been employed by Silicon Labs to reduce overall design time, significantly speeding time to market. Silicon Labs adopted the flow for its new Blue Gecko family of wireless system-on-chip (SoC) devices that provide ultra-low power Bluetooth Smart connectivity for Internet of Things (IoT) applications.
Graphene nanoribbons have perfect zigzag edges from molecules
As reported by the journalNaturein its latest issue, researchers from Empa, the Max Planck Institute in Mainz and the Technical University of Dresden have for the first time succeeded in producing graphene nanoribbons with perfect zigzag edges from molecules. Electrons on these zigzag edges exhibit different (and coupled) rotational directions ("spin"). This could make graphene nanoribbons the material of choice for electronics of the future, so-...
Develop of photonic devices with one-way traffic lanes
Researchers at MIT and other institutions have found a new phenomenon in the behavior of plasmons as they move along tiny ribbons of two-dimensional materials such as graphene and TMDs, which have a hexagonal structure resembling chicken wire. The team found that these plasmons can be separated into two different streams moving in opposite directions at the edges of the ribbons, like traffic on a two-lane highway, without the need for strong magn...
Replacement for silicon devices looms big with latest discovery
Two-dimensional electronic devices could inch closer to their ultimate promise of low power, high efficiency and mechanical flexibility with a processing technique developed at the Department of Energy's Oak Ridge National Laboratory. A team led by Olga Ovchinnikova of ORNL's Center for Nanophase Materials Sciences Division used a helium ion microscope, an atomic-scale "sandblaster," on a layered ferroelectric surface of a bulk copper indium thio...
Transistor photocouplers feature low input current
Expanding its portfolio of low input current transistor photocouplers, Toshiba Electronics Europe has introduced a a pair of 4-channel versions. The TLP292-4 and TLP293-4 operate over a wide temperature range from -55 to +125˚C and can be used for a variety of high-density surface mount applications including PLCs, switching power supplies and simplex or multiplex data transmissions.
MWC 2016: Organic LCD transforms prototype smartwatch
A full colour, conformable organic LCD (OLCD) was shown by FlexEnable at Mobile World Congress 2016 in Barcelona. Curved into a smartwatch form factor, the 0.3mm thick display component demonstrates how mainstream wearables can be brought to life with displays and sensors using flexible electronics.
Modular network appliance features 14nm MPU
The rising trend of IoT has triggered greater demands for reliability and serviceability in network security, cloud computing and data centre operations. To meet this challenging demand, Lanner has unveiled its first Intel Xeon Processor E3-1200 v5 series, based 1U modular network applianceNCA-5210, featuring 14nm microprocessor, the Intel Xeon Processor E3-1200 v5 series, DDR4 memory support and the I/O boosting, comprehensive Intel C236 series ...
Magnetic chips could increase energy efficiency
Engineers at the University of California, Berkeley, have shown for the first time that magnetic chips can operate with the lowest fundamental level of energy dissipation possible under the laws of thermodynamics.The findings, to be published in the peer-reviewed journalScience Advances, mean that dramatic reductions in power consumption are possible—as much as one-millionth the amount of energy per operation used by transistors in modern c...
CMOS SAW-less digital transmitter enables advanced 3, 4 & 5G
imec and Vrije Universiteit Brussel (VUB) have demonstrated a 0.22mm2CMOS resistive charge-based direct launch digital transmitter with -159dBc/Hz out-of-band noise. The achievement paves the way to small form-factor SAW-less transmitter implementations enabling advanced wireless communication systems including all the cellular standards 3G, 4G and future 5G.
