Duolog Technologies tapes out IEEE 802.15.4 ...

Zigbee radio which offers significant time to market reductions for semiconductor customers

Duolog Technologies today announced the tape-out of a 0.13um IEEE 802.15.4/Zigbee radio test chip as part of their 802.15.4 transceiver development program. Duolog Technologies is headquartered in NovaUCD the Innovation and Technology Centre at University College Dublin.

According to Ray Bulger, CEO, Duolog, “This tape-out is a significant step for Duolog along the value added line as a fabless semiconductor house and accelerates our path to the complete 802.15.4 SoC.” He added, “This market leading IP reduces the time to market for our semiconductor customers by more than two years.”

This 802.15.4 transceiver offers a low data rate solution with multi-year battery life and very low complexity. These transceivers operate in an unlicensed, international frequency band. Potential application areas include building automation, industrial automation, health monitoring, and home automation.

The Duolog radio has been carefully designed with a top down approach and includes many novel features and architectures. “This radio has been designed to be best in class in terms of power and current consumption due to the advanced architecture and careful circuit design.” commented Jason Drew, Radio Development Manager, Duolog.

Duolog has also developed an optimised hardware-centric 802.15.4 MAC and baseband designs to ensure an ultra low power transceiver. This hardware intensive solution offers an optimal power and cost balance, ensuring that the system maintains flexibility while minimising silicon area.

Designed exclusively in Duolog’s Analogue/RF IC design centre in Hungary, the tape-out will de-risk major components in the RF signal paths prior to full transceiver tape-out. In addition to the radio components, the power management block is included on the silicon and features an LDO, battery monitor and bias current generators.

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Alliance „OLED Licht Forum“ – Key partner for OLED lighting solutions

Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.

They are united in their passion for OLED (organic light emitting diodes) lighting with all of its unique facets and application possibilities. Thus experts in...

Im Focus: Mars' oceans formed early, possibly aided by massive volcanic eruptions

Oceans formed before Tharsis and evolved together, shaping climate history of Mars

A new scenario seeking to explain how Mars' putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million...
