Carbon-based molecule could be applicable in solar cells
University of Oregon chemists have synthesised a stable and long-lasting carbon-based molecule that, they say, potentially could be applicable in solar cells and electronic devices. The molecule changes its bonding patterns to a magnetic biradical state when heated; it then returns to a fully bonded non-magnetic closed state at room temperature. That transition, they report, can be done repeatedly without decomposition. It remains stable in the p...
War of the currents: AC/DC power
Steve Jobs and Bill Gates - two of the most well-known figures in modern technology and also, one of the industry’s most infamous rivalries. “The only problem with Microsoft is they just have no taste,” Jobs famously stated in 1996. Despite the snide remarks and occasional lawsuits, both Jobs and Gates realised there was room on the IT market for both companies to coexist. The same however, cannot be said for George Westinghouse...
Biosensor could detect molecules linked to cancer
A biosensor developed by researchers at the LNNano in Campinas, São Paulo State, Brazil, detects molecules associated with neurodegenerative diseases and some types of cancer. The device is basically a single-layer, organic, nanometer-scale transistor on a glass slide. It contains the reduced form of the peptide glutathione (GSH), which reacts in a specific way when it comes into contact with the enzyme glutathione S-transferase (GST), lin...
DC/DC converters feature an internal 18V operation driver transistor
Torex Semiconductor has launched the XC9263/XC9264 series of synchronous step-down DC/DC converters with an internal 18V-operation driver transistor and an output current of 500mA. A shift from LDO to DC/DC is gaining strength in recent years in order to reduce standby power consumption. Power consumption also is being reduced in digital audio/visual equipment, large household appliances and industrial equipment and the demand for low power consu...
GaN on SiC RF power transistors suit mobile broadband
Ampleon has introduced its 2nd gen 50V 0.5µm GaN on SiC RF power transistors, dedicated for mobile broadband applications. Providing a 5% improvement in power efficiency compared to LDMOS-based devices and enabling high-power multiband applications, this GaN family also offers a size reduction in the order of 30 to 50%, when compared to similar LDMOS transistors.
GaN-on-Si power transistors suit use in macro wireless basestations
MACOM has announced the latest entries in itsMAGbseries of GaN on Silicon power transistors for use in macro wireless basestations. Based on MACOM’s Gen4 GaN technology, the MAGb-101822-240B0P and MAGb-101822-120B0P power transistors harness the clear performance benefits of GaN in rugged, low-cost plastic packaging, enabling improved cost efficiencies that further distinguish MACOM’s GaN power transistors as the natural successors to...
Imec expands its silicon platform for quantum computing applications
At the Quantum Europe conference, taking place in Amsterdam, Belgian’s nanoelectronincs research centre imec announced that it is ramping-up its R&D activities focused on quantum computing. Imec will implement qubits and supporting nanoelectronic functionality for quantum computing, leveraging its advanced silicon (Si) platform that was established within the framework of its industrial affiliation program with additional support from t...
SiC power devices accelerate automotive electrification
STMicroelectronics has announced advanced high-efficiency power semiconductors for EVs & HEVs with a timetable for qualification to the AEC-Q101 automotive standard. In EVs and HEVs, where better electrical efficiency means greater mileage, ST’s latest SiC technology enables auto makers to create vehicles that travel further, recharge faster and fit better into owners’ lives.
IXYS introduces 40V high-current robust power MOSFETs
IXYS Corporation has announced a generation of high-current Trench devices: 40V TrenchT4 Power MOSFETs. Available at either 270 or 340A current rating, they are optimised for DC to DC converters, synchronous rectification in switched-mode power conversion applications, high current Solid State Relays and motor control applications.
Hitachi adopts Cadence AMS model-based methodology
Cadence Design Systems has announced that Hitachi has adopted a Cadence Analog Mixed-Signal (AMS) model-based methodology and tools to shorten the verification cycle for one of its largest mixed-signal design projects. By upgrading its previous transistor-level methodology to a model-based methodology, Hitachi successfully accelerated mixed-signal verification for this project by 160X and reduced full-chip simulation time to 30 minutes.
