Silicon fingerprint sensor enables low-cost security News & Analysis 5/28/2002 Post a comment Forgot your PIN? Lost your access card? Password hacked? Put these security woes to bed. Your fingerprint neatly carries all that's needed to ensure secure access for a host of applications. A capacitive-based sensing chip makes fingerprint access practical.
Valley control: One power management trick for new generation PCs News & Analysis 5/15/2002 Post a comment Pentium-based computers can demand up to 60 amps from 1-V line. But powering the CPU core is only one challenge: clocks, peripherals, PCI and graphics bus drivers - even DDR memory - demand a variety of voltages and currents from an otherwise "Green PC." IMVP demands more aggressive power management techniques. This Fairchild engineer explores the main challenges for powering both desktop and notebook PCs.

Flexible I/O speeds data switch News & Analysis 5/13/2002 Post a comment A new concept for crossbar switching fabrics that targets unused switching paths will be presented at the Custom Integrated Circuits Conference this week.
Innovative ideas leap design hurdles at CICC News & Analysis 5/13/2002 Post a comment The IEEE Custom Integrated Circuits Conference (CICC) has been the prime venue for new perspectives on the toughest problems facing IC designers. This year's event, to be held this week in Orlando, Fla., offers a fresh crop of innovative circuit design ideas, some of which are excerpted in this week's Focus section.
Europe's austriamicrosystems hones strategy for push into global markets News & Analysis 5/10/2002 Post a comment SAN JOSE -- Chip maker austriamicrosystems AG of Austria is pushing hard to put itself on the semiconductor map--globally speaking. The 22-year-old semiconductor company says it is taking aggressive steps to make a name for itself outside of Europe as a major supplier of ASICs and specialty foundry processes for worldwide customers.
GaAs IC revenues will recover with 17% growth in 2002, says new report News & Analysis 5/6/2002 Post a comment NEW TRIPOLI, Pa. -- After plunging 33% in 2001, the market for gallium-arsenide (GaAs) integrated circuits is now expected to grow 17% and reach $1.9 billion in 2002 with cellular phones applications helping to revive revenues this year, said a new report from The Information Network here. The research firm is predicts that worldwide GaAs IC revenues will reach $4.2 billion in 2005.
Infineon forms new wireless unit, de-emphasizes cordless phone chip activities News & Analysis 5/2/2002 Post a comment MUNICH -- Infineon Technologies AG today announced formation of a new Local Area Wireless business unit to address applications using Bluetooth radio-frequency (RF) connections and wireless local area networking (WLAN) technologies. The Munich chip maker also indicated that the move was part of a new strategy to refocus resources to avoid price wars in the digital cordless phone segments.
A new true single supply power amplifier solution for dual and tri-band handsets News & Analysis 5/1/2002 Post a comment Until recently, the depletion-mode GaAs antenna drivers used in most cell phones required a negative rail generator. This paper, reprinted from Microwave Engineering in the UK, describes the implementation of a three-stage dual-band single supply RF power amplifier for cellular handsets. With output matching, this device can be easily used in tri-band applications (GSM900/DCS1800/PCS1900). The IC is fabricated using 1m pHEMT enhancement mode technology developed specifically for single 3.6-V sup
So many callers, so little time: PFT engine slices wideband frequency channels News & Analysis 5/1/2002 Post a comment RF Engine's Vectis family DSP cores, announced April 17, perform complex filtering faster than any general-purpose processor. In addition to channel selection and filtering for cellular applications, Vectis' developer - a military contractor gone commercial - believes the cores support VDSL communications as well as signal intelligence for defense. The vectis4000R2 core, which processes data continuously at a 200 Msamples/s rate, can be implemented with room-to-spare on Xilinx Virtex/E FPGA. Th
Blog Make a Frequency Plan Tom Burke 17 comments When designing a printed circuit board, you should develop a frequency plan, something that can be easily overlooked. A frequency plan should be one of your first steps ...
