System Bits: Dec. 8
By Ann Mutschler - 08 Dec, 2014 - Comments: 0

Path to quantum transistors An odd, iridescent material that's puzzled physicists for decades turns out to be an exotic state of matter that could open a new path to quantum computers and other next-generation electronics, according to University of Michigan physicists. The researchers have been able to confirm that several properties of the compound samarium hexaboride that raise hopes for... » read more

Power/Performance Bits: Dec. 8

Light in lieu of wires In a development that could eventually lead to computers that use optics rather than electricity to carry data, Stanford engineers have designed and built a prism-like device they call an ‘optical link’ that can split a beam of light into different colors and bend the light at right angles. The optical link is a tiny slice of silicon etched with a pattern that res... » read more

Cost Reduction, Power Management Get More Intense In IoT
By Ann Mutschler - 04 Dec, 2014 - Comments: 0

Power has become a consideration even if there is a plug in the wall. But for applications sitting out who knows where in the [getkc id="76" comment="Internet of Things"] (IoT), it is more than a consideration. It is one of the primary requirements, given the small size of these devices, rivaled only by cost. Reflecting on what brought the industry to this point, Aveek Sarkar, vice president... » read more

Architecting For Optimal Interface IP Integration
By Ann Mutschler - 04 Dec, 2014 - Comments: 0

Semiconductor Engineering sat down to discuss the design and integration of complex interface IP with Ty Garibay, VP of engineering at Altera; Brian Daellenbach, president of Northwest Logic; Frank Ferro, senior director of product management for memory and interface IP at Rambus; Saman Sadr, director of analog design at Semtech; and Navraj Nandra, senior director of marketing for analog/mixed ... » read more

Power Limits Apps In The IoT
By Ann Mutschler - 04 Dec, 2014 - Comments: 0

The applications in the IoT are seemingly limitless, but the power is one thing that can’t be. Mary Ann White at Synopsys reminded me that a lot of the energy harvesting devices are super low power and there is a reason why they use just a simple LCD-type display. But we agree it would be so cool if we could have color LCDs that still only consume low power. Of course, I have no doubt tha... » read more

A graphene layer reads optical information from nanodiamonds electronically It is assumed that nitrogen-vacancy centers in diamonds could be used to construct vital components for quantum computers but reading optically-written information electronically from them has not been possible. Now, by using a graphene layer, a team of scientists headed by the Technische Universität München (TUM) ha... » read more

Power/Performance Bits: Dec. 2

Harvesting more of the sun's energy As solar panels become less expensive and capable of generating more power, solar energy is becoming a more commercially viable alternative source of electricity and today’s photovoltaic cells can only absorb and use a small fraction of that light, which means a significant amount of solar energy goes untapped. However, a new technology created by research... » read more

System Bits: Nov. 25

Biological circuits In recent years, researchers have made progress in the design and creation of biological circuits which can take a number of different inputs and deliver a particular kind of output — like electronic circuits. However, while individual components of such biological circuits can have precise and predictable responses, those outcomes become less predictable as more such ele... » read more

Better photodetectors Photodetectors are semiconductor devices that convert incoming light into electrical signals used in a vast array of products, from visible and infrared light detection systems to television remote controls. Meanwhile, perovskite is an organic-inorganic hybrid material with a crystal structure that is very efficient at converting light into electricity, and in recent year... » read more

Filling In The Gaps For Mixed-Signal Verification
By Ann Mutschler - 24 Nov, 2014 - Comments: 0

Semiconductor Engineering sat down to discuss mixed-signal verification with Haiko Morgenstern, Mixed-Signal Verification Group Staff Engineer at Infineon; Dr. Gernot Koch, CAD Manager at Micronas; Pierluigi Daglio, AMS Design Verification Flows Manager at STMicroelectronics; and Helene Thibieroz, AMS marketing manager at [getentity id="22035" e_name="Synopsys"]. What follows are excerpts of th... » read more
