University of California at Riverside researchers report their development of ultra-efficient photodetector devices using transition-metal dichalcogenides, an ultrathin 2D material. The team stacked two atomic layers of tungsten diselenide on a layer of molybdenum diselenide to form the photodetector, which is nearly transparent, and applying a small charge to the pixel-size device to increase its efficiency by 350%.
Renesas Electronics plans to release an expanded version of the e² studio integrated software development environment during the first quarter of 2018. The integrated development environment will support the company's R-Car V3M technology and can be used to write code for advanced driver-assistance systems and automated driving.
GaN Systems has introduced the GS61004B-EVBDC evaluation platform, which pairs the company's GS61004B power transistors with Peregrine Semiconductor's PE29102 gallium nitride transistor driver. The evaluation platform is priced at $99.
Next-generation memory devices are posing technical challenges for automatic test equipment, this analysis notes. VLSI Research forecasts the global market for memory test equipment will be about $670 million in 2017, compared with $470 million last year.
Google on Tuesday detailed its internally designed Pixel Visual Core system-on-a-chip, which works with the camera in the company's new Pixel 2 smartphone model. Google's move into designing chips for its consumer products, just as Apple and Samsung Electronics do, could prove an issue for Qualcomm, which supplies the Snapdragon application processors used in Google's phones.
Samsung Electronics says it has completed development of a manufacturing process for chips with 8-nanometer features that the company will use for Qualcomm and other foundry customers. The 8 Low Power Plus process is said to be 10% more energy efficient and uses 10% less space than Samsung's 10LPP process, which went into volume production a year ago.
Nanya Technology is making volume shipments of 4-gigabit DDR3 DRAMs with 20-nanometer features, with plans to start volume production of 20nm DDR4 memories before the end of this year. The company reports net profit of $283.9 million for the third quarter, an increase of 32.1% from the second quarter, while consolidated revenue rose 5.3% from Q2.
Knowles recently unveiled the IA8505 audio processor for near- and far-field voice applications, aimed at ear-worn devices, mobile phones and internet of things items. The chip has an open digital signal processor platform with four heterogeneous cores and can be used for machine learning.
Robert Blake, president and CEO of Achronix Semiconductor, talks about developments in the embedded field-programmable gate array field in this interview. "It's high-performance compute with very low latency, so this can apply to any application that needs closely attached compute," he says about eFPGAs.
