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

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

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

Making Models Interoperable
By Ann Mutschler - 20 Nov, 2014 - Comments: 0

As engineering teams raise the vision of their design to a higher level of abstraction, the use of behavioral modeling is growing. While not ubiquitous, the concepts are gelling, which at least is helping the industry discuss the technology more intelligently and determine where automation makes sense. One of the biggest concerns with behavioral modeling is what engineering teams want to do ... » read more

Measuring Verification Accuracy
By Ann Mutschler - 20 Nov, 2014 - Comments: 0

[getkc id="10" kc_name="Verification"] is the unbounded challenge that continues to confound engineering teams across the globe, who want to know when "enough" is "good enough" to proceed to tapeout. The answer is not straightforward, and it includes more variables than in the past, particularly around power. Harry Foster, chief verification scientist at [getentity id="22017" e_name="Mentor ... » read more

A lighter, cheaper radio wave device Researchers at The University of Texas at Austin reported that they have achieved a milestone in modern wireless and cellular telecommunications through the creation of a radically smaller, more efficient radio wave circulator that could be used in cellphones and other wireless devices. The researchers said the circulator has the potential to double the ... » read more

Phase transitions between liquid, gas Researchers from the University of Tokyo and Tokyo Institute of Technology reminded that materials change their form between three states -- solid, liquid, and gas -- depending on factors such as temperature and pressure. However, a phase transition does not necessarily occur between liquid and gas, and they can continuously transform from the one to the o... » read more
