RF design team raises funds for CMOS PA initiative News & Analysis 7/30/2007 Post a comment Is it possible to make a CMOS power amplifier for 3G cell phone applications that can operate with the same power efficiency and robustness as a gallium arsenide version? ACCO Semiconductor (Saint Germain en Laye, France) believes it has found a way to do just that and with its patent applications in hand is hoping to reap the benefits in a multibillion dollar market.
Portable devices drive power management demand News & Analysis 7/27/2007 Post a comment Market research firm iSuppli Corp. projects the global power management semiconductor market to grow significantly over the next few years, driven in part by rising demand from portable electronic equipment manufacturers.
Dialog stabilizes after crash News & Analysis 7/24/2007 Post a comment In the second quarter, Dialog Semiconductor could stabilize its situation after last year's refocusing process. The company even returned to an albeit small growth.
DC/DC controller draws 30-microamps in automotive systems Product News 7/24/2007 Post a comment Check out Linear Technology's ultra-low quiescent current, two-phase dual output synchronous step-down DC/DC controller that draws only 30µA when one output is active and only 50µA when both outputs are active, making it well-suited for automotive applications.
Bringing ZigBee designs to high volume Design How-To 7/23/2007 Post a comment The ZigBee wireless networking standard is fostering a wide range of newly untethered products for applications such as home and building automation, utility metering and building security. Devices without the cost or power budgets to support wireless connectivity now can leverage proven ZigBee technology for new innovation possibilities. However, "going wireless" brings new test challenges for designers unfamiliar with radio technology.
Wacker builds granular polysilicon line News & Analysis 7/23/2007 Post a comment In addition to existing expansion plans, Wacker Chemie plans to erect an additional polysilicon manufacturing site in Burghausen, Germany. Unlike most other polysilicon production lines, the new production site will produce granular silicon.
Startup launches microwave-powered light bulb News & Analysis 7/23/2007 Post a comment Startup company Ceravision Ltd. (Milton Keynes, England) has said it has invented a microwave-powered light bulb that is more efficient than filament or fluorescent lighting and with a long stable lamp life. The company said it has prototypes available for evaluation by lamp and electronics manufacturers.
Infineon bets big on automotive growth News & Analysis 7/19/2007 Post a comment Driven by energy efficiency requirements, demand for comfort and safety functions and by the growing motorization in emerging markets, the automotive semiconductor market grows faster than the overall chip market. Within the automotive segment, Infineon presently grows much faster than the total market, said Peter Bauer, Infineon board member and head of the company's AIM (Automotive, Industrial, Multimarket) division last Thursday (July 19) at the roll-out of a new microcontroller chip for safe
Vishay rolls out ChipFET power MOSFET line Product News 7/18/2007 Post a comment Vishay Siliconix PowerPAK ChipFET power MOSFETs replace TSOP-6 devices with 75% lower thermal resistance in 33% smaller footprint, and offer the same 3-W maximum power dissipation as larger SO-8 devices, but provide greater thermal efficiency.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
