Zigzag edges could make graphene the material of choice in spintronic devices
25.03.2016 - 23:18

Researchers from Empa, the Max Planck Institute in Mainz and the Technical University of Dresden claim to have produced graphene nanoribbons (GNR) with perfect zigzag edges. Electrons on these zigzag edges are said to exhibit different - and coupled - rotational directions. This is said to be a step towards creating the spintronic devices of the...



Massive MIMO system transmits 1.59Gbit/s over 20MHz channel
25.03.2016 - 23:14

New research by engineers from the Universities of Bristol and Lund, working alongside National Instruments, has demonstrated how a massive antenna system can increase spectrum efficiency by 12 times, compared with current 4G cellular technology. Multiple antenna technology – MIMO – is used in Wi-Fi routers and 4G systems and norm...



32bit MCU portfolio expanded
25.03.2016 - 23:12

Renesas has expanded its 32bit MCU portfolio with the addition of the RX24T group. Based on the RXv2 CPU core, the devices are said to offer enhanced performance, a decrease of 30% in development time and additional instructions that accelerate performance and energy efficiency in a range of applications. There are six devices in the range, w...



High efficiency integrated power stages
25.03.2016 - 23:10

With a power efficiency as high as 96%, devices from Infineon’s latest integrated power stage family can be combined with digital PWM power management controllers to provide a full multiphase voltage regulation system solution for server, storage, client and communications systems. The devices – said to reduce power loss and to si...



Laser writing could enable microbatteries in chips
25.03.2016 - 23:06

As demand grows for thinner and lighter microelectronic devices, manufacturers can be challenged when it comes to getting power sources into the smaller space. Looking to address the issue, researchers at the University of Missouri have developed a laser writing technique that enables energy sources to be created in virtually any shape. Accordin...



Guard against fakes, says ESCO
23.03.2016 - 23:20

ESCO’s latest anti-counterfeiting forum highlighted some of the problems facing those procuring hard to get components. Gary Moffat, UK sales manager for Retronix, said: “It’s not always possible to wait for 24 weeks for a device and there’s pressure on purchasers to get products to customers.” While not all s...



Power supplies for body floating medical applications
23.03.2016 - 23:18

A series of power supplies for medical applications BF (Body Floating) has been announced by Powerbox. Complying with IEC 60601-1-2: 2014 (4th edition), the seven devices in the OBS01 series deliver 1100W, but can support peak demands of 1250W. Offering an efficiency of up to 89%, the devices are said to meet conducted and radiated EN55011 cl...



Tektronix unveils 1GHz optically isolated measurement system
23.03.2016 - 23:15

Tektronix has unveiled its IsoVu technology at APEC 2016, the technology is claimed to offer complete galvanic isolation between a device under test (DUT) and an oscilloscope through the use of electro-optical sensors. Tektronix says it will be the industry’s first measurement solution capable of accurately resolving high bandwidth differe...
