Another Beyond CMOS Candidate
Theory of Nano-Electron-Fluidic Logic (NFL): A New Digital “Electronics” Concept
A new digital “electronics” concept is introduced. The concept, called nano-electron-fluidic logic (NFL), is based on the generation, propagation and manipulation of plasmons in a two-dimensional electron gas behaving as an electron fluid. NFL gates are projected to exhibit femtojoule power dissipations and femtosecond switching speeds at finite temperatures. NFL represents a paradigm shift in digital technology, and is poised as a strong candidate for “beyond- CMOS” digital logic.
* Operates with far less heat and more efficient energies (femtojoules)
* Faster switching speeds (femtosecond)
* higher density potential for devices
* Terahertz operating speeds for chips
* Propogation velocity of electron fluid is hundreds of times faster than electrons in current CMOS
* Device construction is compatible with current lithography
Nano-Electron Fluidic Logic (NFL) Device patent application 2009026764
A nano-electron fluidic logic (NFL) device for controlling launching and propagation of at least one surface plasma wave (SPW) is disclosed. The NFL device comprises a metallic gate patterned with a plurality of terminals at which SPWs may be launched and a plurality of drain terminals at which the SPWs may be detected. A wave guiding structure such as a 2 DEG EF facilitates propagation of the SPW within the structure so as to scatter/steer the SPW in a direction different from a pre-scattering direction. A bias SPW is excited by an application of a control SPW with a momentum vector at an angle to the bias SPW and a control current with a wavevector which scatters the bias SPW in the direction of at least one output SPW, towards a drain terminal. The NFL device being rendered with device speed as a function of SPW propagation velocity.
* speed of the device is a function of SPW propagation velocity in terahertz switching frequencies.
A previous paper from 2004 by Héctor J. De Los Santos: NanoMEMS SYSTEMS ON CHIP
NanoMEMS exploits the convergence between nanotechnology and microelectromechanical systems (MEMS) brought about by advances in the ability to fabricate nanometer-scale electronic and mechanical device structures. While the “nano” aspect of this field is in its infancy, and is not expected to reach maturity until well into the 21st century, its “MEMS” aspect is a topic of much current and near-term impact in, for instance, RF/Wireless communications. In this context, we discuss the fundamentals of NanoMEMS, in particular, as it relates to its most speculative and futuristic paradigms and applications, and then focus on the RF/Wireless MEMS aspect, specifically in its role as enabler of ubiquitous wireless connectivity.
Intel and Sun Micro Product Roadmap Updates
* Intel will show off “Westmere,” the first processors built using a 32 nanometer (nm) manufacturing process.
* CPU manufacturing shrank from 65nm to 45nm to 32nm and next to 22nm.
* The next chip architecture will come in 2010, in the form of the new architecture codenamed “Sandy Bridge,” which will also be disclosed at this month’s IDF. Intel’s roadmap is process shrinkage and then better architecture and then process shrink etc… (tick-tock)
* This new-generation high-k metal gate transistor formula will give Intel “a 3+ year advantage in addressing leaky and energy inefficient transistors,” according to a blog post from Intel spokesman Bill Kircos Intel has shipped >200 million 45nm CPUs using high-k+ metal gate transistors.
* For the first time, Intel has developed a full-featured SoC process technology to complement the CPU-specific technology. This version is for our smarter System on Chip (SoC) product efforts, which emphasize lower power transistors
* Intel NMOS transistors now have 19% performance improvement over their 45nm counterparts and our PMOS transistors now have a 28% performance improvement over their 45nm counterparts.
* Another IDF highlight: Nehalem-based chips codenamed “Jasper Forest” and designed for the embedded and storage sectors. This family of products will bring Nehalem to the embedded market, offering integrated PCI Express (PCIe) and an integrated I/O hub in a dual-processor Xeon processor.
* Nehalem will allow for much faster and denser storage and communications solutions such as IPTV, VoIP, NAS, SAN and wireless radio network controllers
The UK Register has information on the Sun Sparc Roadmap. The 16-core “Rock” UltraSparc-RK processor for Sun’s once-and-never “Supernova” line of servers is not on the roadmap. The one-page roadmap is one given Sun’s customers – and presumably also Fujitsu’s customers – have been shown about the future Sparc processor lineup.
June 2009 Sun Roadmap
A long way off in late 2010 or early 2011, the Sparc Enterprise server lineup gets a speed boost to 3 GHz with the Jupiter-E chips.
After that, in 2012, Sun has made no commitment to the kicker line of Fujitsu “Advanced Product Line 2″ servers coming from Fujitsu. These APL2 machines are presumably to be based on the “Venus” eight-core Sparc64-VIII processor, which has a Sparc64-VIIIfx variant aimed at supercomputers. That Sparc64-VIIIfx chip will be used in a 10 petaflops massively parallel machine being built by Fujitsu and paid for by the Japanese government under the 1.2bn Project Keisoku effort.
All of this is subject to change, and some of it most certainly will once Oracle takes control of Sun.
Avago intros pair of miniature 0.25W analog variable gain amplifiers for cellular infrastructure apps
Housed in a compact 5 mm by 5 mm by 1.1 mm, 10-lead module package, Avagos ALM-80110/80210 variable gain amplifiers feature a common footprint for easy integration into most base station designs. Additionally, these amplifiers offer high linearity and dynamic range performance and support all major cellular bands in North America, Europe and Asia.
The ALM-80110 operates from 0.4 to 1.6 GHz, while the ALM-80210 operates from 1.6 to 2.7 GHz and are ideal for use in WLL, WLAN, transmitter receiver gain control, and temperature compensation circuitry applications. Both amplifiers provide an exceptionally high Output 3rd Order Intercept Point (OIP3) level of 40 dBm, which is maintained over a wide attenuation range. Additionally, these devices feature a wide gain control range, low power consumption, as well as excellent input and output return loss.
Avagos ALM-80110/80210 variable gain amplifiers incorporate a unique solution which integrates Avagos high linearity 0.25W amplifiers and silicon PIN diode-based pie attenuator into a miniature multiple-chips-on-board (MCOB) module package.
Both of these amplifiers feature broadband fully-matched input and pre-matched output for ease of use and require a minimum amount of external RF matching components. Moreover, the high linearity and dynamic range performance of these amplifiers is achieved through the use of Avagos proprietary 0.25 um GaAs enhancement-mode pHEMPT process and low distortion silicon pin diode technologies.

Increased healthcare and military spending sustains demand in world AC-DC switching power supplies market
The consumption of AC-DC switching power supplies is driven by the demand for electrical and electronic equipment used in various applications such as IT, telecom, industrial and consumer electronics. The market for AC-DC switching power supplies is mature and hence influenced by economic trends.
The economic slowdown has reined the progress in the IT/telecom, consumer electronics and industrial segments, which account for a sizeable portion of the switching power supplies market revenues. However, prospects are likely to improve once the economy recovers.
“Though some end-user segments such as light emitting diode (LED) lighting and set-top boxes have displayed positive demand, revenues from other applications including industrial process control, automated test equipment, telecom and networking equipment, and television were weak during the last quarter of 2008 and the first quarter of 2009,” notes the analyst of this research.
However, continuing demand from medical applications and the military is likely to sustain the AC-DC switching power supplies market through the prolonged economic downturn. Ageing population and the continuous need for quality healthcare drives steady uptake of power supplies used in diagnostic, imaging and other critical medical equipment.
These products are more quality-centered rather than price focused due to the critical nature of the applications. Further, governments across the world have increased military spending to counter terrorist activities, and hence demand from the military segment for sophisticated equipment with complex instrumentation is expected to increase.. This bodes well for the AC-DC switching power supplies market.
Slow adoption of digital power techniques and increased outsourcing to Asia Pacific region impacts market dynamics
Power supplies that incorporate digital control offer improved efficiency, reduced parts count, and reduced size. Hence, expectations were high for digital power management and digital control to boost market potential for AC-DC power supplies market a few years ago.
However, original equipment manufacturers are hesitant to pay for the extra costs incurred for these additional benefits, restraining the uptake of digital power management and digital control in various applications. Moreover, the digital power supplies are not price competitive when compared to their analog counterparts.
Market participants have to intensify efforts to make these products more cost effective to improve the overall market opportunity in digitally controlled switching power supplies.
