Getting 12-bits of Resolution out of your 10-bit A/D News & Analysis 8/26/2003 Post a comment Cost sensitive designs benefit from using lower resolution A/Ds and simple signal processing techniques. Including software solutions in you're A/D selection process can reduce your system cost without sacrificing performance. In Part 1 of this multi-part tutorial, FAE Fugerer looks at sample "averaging" as a means of increasing A/D resolution. In Part 2, he examines "oversampling." (Be sure too to look at the Appendix material that accompanies these articles.)
Chips charge up for lithium-ion Product News 8/21/2003 Post a comment A variety of linear and switch-mode chips continues to emerge in the IC battery charger market, triggered by shrinking real estate requirements and the need for improved thermal management in charging lithium-ions, today's battery of choice.
Programmable analog chases discrete market pricing News & Analysis 8/19/2003 Post a comment This isn't exactly "I told you so." Or maybe it is: Anadigm is dropping the entry price for its programmable analog chips below $5 to be more competitive with the discrete devices that they are designed to replace. Crista Souza reports.
Counterfeit parts nettle buyers News & Analysis 8/19/2003 Post a comment Though bound by the privileges of World Trade Organization (WTO) membership to police its industries, China's efforts to stamp out IP theft and trafficking in counterfeit electronic components appear to be gaining little ground, according to industry observers. And more than one US company has gotten stung. EBN's Laurie Sullivan has this report.
Analog/mixed-signal optimization tool supports 1394 PHY design News & Analysis 8/18/2003 Post a comment The analog IC designer must constantly juggle tradeoffs between power, noise, silicon area, and bandwidth, says Analog Design Automation. The ability to evaluate a number of separate designs in the same EDA flow " and to display the results graphically on the same screen " helps the designer balance tradeoffs and improve time to market. This article, from the August 18th issue of PA magazine, suggests how.
Chip designers move back from bleeding edge News & Analysis 8/18/2003 Post a comment The Hot Chips conference has long been the showcase for processors that hit blistering speeds by way of advanced architecture, bleeding-edge processes and full-custom design. But new approaches are emerging based on unconventional semi-custom design methodologies that wring the same kind of speed from familiar architectures and ordinary processes. EE Times' Ron Wilson is on the scene.
Uncrackable keys require hardware RNGs News & Analysis 8/13/2003 Post a comment Have you been attacked by the Lovsan worm virus? Time to look again at Nic Mokhoff's contributed article section in EE Times' InFocus section on network security. Here Ubicom CTO David Fotland shows hardwired logic that can generate random numbers based on network noise.
Building secure networks for comms work News & Analysis 8/13/2003 Post a comment Have you been attacked by the Lovsan worm virus? Time to look again at Nic Mokhoff's contributed article section in EE Times' InFocus. Here Actel's Jon Ewald offers an advisory on the use of FPGAs in secure networks.
802.11a/b Card: Downconversion delivers Teardown 8/13/2003 Post a comment Let's face it"wires are so yesterday, says David Carey in this teardown report written solely for Planet Analog. Never mind going into an electronics store, even urban coffee bars are likely to feature 802.11 wireless connectivity. The WLAN industry is twisting 802.11 into new shapes in order to get higher throughput and less crowded spectrum. This Netgear card operates at either 2.4 or 5 GHz, and includes a number of surprising IC brands.
Design, programming and verification of 3G basestations Design How-To 8/8/2003 Post a comment Concern over the complexity of electronics system design is widespread, but it is felt particularly strongly in wireless communications where engineers struggle to get closer and closer to the Shannon limit the theoretical limit of information transmission in the presence of noise.
Speed, power crunch looms for wireless Design How-To 8/8/2003 Post a comment Engineers developing products for the wireless market face a daunting challenge: provide all the complex enhancements required to support new air interfaces plus full support of legacy-and do it at a price, per equivalent voice channel, that's significantly lower than today's cost of supporting the legacy functions alone.
Interviewing 101 with today's twist Blog 8/6/2003 Post a comment In today's results-oriented business environment, it won't be your drippy nose or frayed cuffs the interviewer will be staring at. "What have you done for me lately?" applies to the job candidate as well as the 20-year employee. Our veteran analog recruiter suggests figuring out fast what a prospective employer really cares about, and control the interview by showing how you can accomplish just that.
UMC to buy out Infineon stake in UMCi News & Analysis 8/6/2003 Post a comment Infineon Technologies A.G. said it has agreed to sell its minority stake in UMCi Pte. Ltd., to majority holder United Microelectronics Corp. for an undisclosed amount in a move that the German semiconductor company said would give it access to all of UMC's wafer fabs.
Satisfying the Analog Interface Demands of VDSL News & Analysis 8/4/2003 Post a comment ADSL technology has been a resounding success and the number of subscribers is expected to continue
