Programmable analogue makes a resurgence 2014

Posted by Mohammad Ajmal on 10:34 AM
Programmable analogue makes a resurgence
Description:
Some of the earliest computers used for controlling processes featured analogue architectures because they were much more responsive than valve based logic circuits. But they needed to be custom designed and succumbed to the more flexible – and ultimately cheaper – digital computer.
However, advances in programmable analogue technology may see not just the resurgence of analogue computing in areas where digital works out to be more power hungry, but also a way of supporting analogue functions on increasingly dense but highly variable SoCs.




Although switched capacitor circuitry is a good match for CMOS, switching imposes a limit on the achievable bandwidth of the circuit. Continuous time architectures can, in principle, process higher frequency signals. Zetex' TRAC architecture achieved bandwidths more than an order of magnitude higher than its switched capacitor peers in the late 1990s and early 2000s. One architecture developed at the University of Freiburg in the last five years, has achieved unity gain of close to 200MHz. 



The recognition that most analogue circuitry now drives a digital core has led to the appearance of devices such as Cypress Semiconductor's PSoC and, more recently, Maxim Integrated's MAX11300. These put a series of analogue building blocks onto a digital chip. In the case of the PSoC, analogue functions are under the control of an on chip microcontroller. The Maxim part, meanwhile, is configured at design time to link different mixed signal elements such as A/D and D/A converters together directly.

Researchers demonstrate ultrafast charge transfer in new family of 2-D semiconductors 2014

Posted by Mohammad Ajmal on 12:09 AM

Description:
ew argument has just been added to the growing case for graphene being bumped off its pedestal as the next big thing in the high-tech world by the two-dimensional semiconductors known as MX2materials. An international collaboration of researchers led by a scientist with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) has reported the first experimental observation of ultrafast charge transfer in photo-excited MX2 materials. The recorded charge transfer time clocked in at under 50 femtoseconds, comparable to the fastest times recorded for organic photovoltaics..

Changing temperature powers sensors in hard-to-reach places 2014

Posted by Mohammad Ajmal on 12:05 AM

Description:
The clock, powered by changes in temperature and atmospheric pressure, was invented in the early 17th century by a Dutch builder. Three centuries later, Swiss engineer Jean Leon Reutter built on that idea and created the Atmos mechanical clock that can run for years without needing to be wound manually.
Now, University of Washington researchers have taken inspiration from the clock's design and created a power harvester that uses natural fluctuations in temperature and pressure as its power source. The device harvests energy in any location where these temperature changes naturally occur, powering sensors that can check for water leaks or structural deficiencies in hard-to-reach places and alerting users by sending out a wireless signal.
"Pressure changes and temperature fluctuations happen around us all the time in the environment, which could provide another source of energy for certain applications," said Shwetak Patel, a UW associate professor of computer science and engineering and of electrical engineering.

Ultra sensitive biosensor from molybdenite semiconductor developed 2014

Posted by Mohammad Ajmal on 11:58 PM


Description:
 An atomically thin, two-dimensional, ultrasensitive semiconductor material for biosensing developed by researchers at UC Santa Barbara promises to push the boundaries of biosensing technology in many fields, from health care to environmental protection to forensic industries.
Based on molybdenum disulfide or molybdenite (MoS2), the biosensor material -- used commonly as a dry lubricant -- surpasses graphene's already high sensitivity, offers better scalability and lends itself to high-volume manufacturing. Results of the researchers' study have been published in ACS Nano.
"This invention has established the foundation for a new generation of ultrasensitive and low-cost biosensors that can eventually allow single-molecule detection -- the holy grail of diagnostics and bioengineering research," said Samir Mitragotri, co-author and professor of chemical engineering and director of the Center for Bioengineering at UCSB. "Detection and diagnostics are a key area of bioengineering research at UCSB and this study represents an excellent example of UCSB's multifaceted competencies in this exciting field."

Apple TV 2014

Posted by Mohammad Ajmal on 10:35 PM

Description:
Over the course of the last three years, Apple has taken an even greater interest in the Apple TV, heavily boosting its functionality through both content offerings and hardware improvements. In addition to content from the iTunes Store, the Apple TV now offers more than 20 different channels, ranging from HBO GO to Netflix, with further deals in the works.

Apple's growing focus on content deals, along with specific comments from Steve Jobs on the company's interest in the television arena, has spurred countless rumors questioning the future of the device. Speculation has suggested that the Apple TV could be expanded into a gaming device, a cable box replacement, a full-blown television set, or a combination of all three.

Though the exact future of the Apple TV is still up in the air, it is clear that Apple has ambitious plans for both the device and its ultimate role in the television industry. As Apple CEO Tim Cook has repeated multiple times, television remains an area of "intense interest" for the company

iPhone 6 Apple's 2014

Posted by Mohammad Ajmal on 10:27 PM


Description:


Along with a larger screen, both models of the iPhone 6 are expected to adopt design elements from the iPad and the iPod touch. Alleged iPhone 6 schematics and part leaks have suggested the iPhone 6 will be considerably thinner than the current iPhone 5s, which is 7.6 mm. The final version of the 4.7-inch iPhone 6 is said to be 6.9 mm thick, 138 mm long, and 66 mm wide. The 5.5-inch iPhone 6 is said to be 7.1 mm thick, 158 mm long, and 78 mm wide.

The phones will also include rounded iPad-style corners, pill-shaped volume buttons, thick antenna bands, a rounded True Tone dual-LED flash, an embedded Apple logo, and a power button located on the right side of the device.

Rumors have suggested at least some models of the iPhone 6 might feature a durable sapphire display and both the 4.7 and 5.5-inch iPhone 6 are expected to see camera improvements. The larger 5.5-inch iPhone 6 might incorporate Optical Image Stabilization as a differentiating feature from the 4.7-inch iPhone 6, and it is also possible that the larger iPhone 6 will be the only model with a 128GB storage capacity, which has been mentioned in rumors and seen in leaked schematics. As a result, the larger phone might have a higher price tag.

Images of a completed logic board have suggested the 4.7-inch iPhone 6 will continue to offer 16GB of storage space at the low end, along with 1GB of RAM, support for NFC, and a Qualcomm MDM9625M LTE Modem that supports speeds of up to 150 Mbps. Specifications for the larger 5.5-inch iPhone remain unknown, but the device will likely include many of the same components.
