At today’s IEEE International Solid State Circuit Conference, IMEC introduced its prototype of a 60GHz multiple antenna receiver, and invites industry to join its 60GHz research program.
The 60GHz band offers massive available bandwidth that enables very high bit rates of several Gbits-per-second at distances up to 10 meters (about 33 feet). To make the 60GHz technology cost-efficient to manufacture, low power and affordable in consumer products, IMEC has built its RF solution in a standard digital CMOS process thereby avoiding the extra cost of alternative technologies or dedicated RF process options.
The second industry goal is to overcome high path losses at mm-wave frequencies by using a phased antenna array approach. IMEC’s prototype uniquely addresses this problem by implementing a programmable phase shift of various incoming signals, which is necessary for beam-forming.
IMEC’s device contains two antenna paths, each consisting of a low-noise amplifier and a down-conversion mixer. The programmable phase shift is realized on the same chip. It starts from the quadrature signals of an on-chip quadrature voltage-controlled oscillator (QVCO). This QVCO design combines the highest oscillation frequency with the largest tuning range ever reported in CMOS.
IMEC’s multiple antenna receiver is the first step towards a complete CMOS-based phased array transceiver for 60GHz wireless personal area networks that envisage multi-gigabit-per-second applications such as fast kiosk downloading, wireless high-definition multimedia interface (HDMI), and other applications.
In the next phase of development, IMEC plans to implement four antenna paths using 45nm CMOS technology and to integrate other subsystems such as the phase-lock loop (PLL), analog-to-digital converter (ADC) and the patch-antenna array itself. IMEC will also begin initial experiments for a power amplifier.
These results were achieved in the unique multi-disciplinary 60GHz technology program. The research combines system-level aspects, algorithms, CMOS IC design, antenna design and module design, which target a low power 60 GHz communication link based on adaptive beamforming using multiple antennas aligned with ongoing standardization activities.

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.
Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...
Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.
Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.
Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.
After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.
"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
