Dealing with the EDGE Evolution News & Analysis 9/24/2002 Post a comment EDGE is being touted as the next wireless plateau in the US sector. But to get there, designers must first deal with new modulation schemes, QoS support mechanisms, link adaptation, and more.
Oxide isolation ramps next-gen process News & Analysis 9/23/2002 Post a comment Roughly every two years for the last decade and a half, a scaled CMOS technology generation has been introduced with about 70 percent smaller linear dimensions than its predecessor and transistors approximately 30 to 40 percent faster.
ICs tailored for exotic substrates News & Analysis 9/23/2002 Post a comment As we move into the 21st century, substrate manufacturers will acquire more responsibility in IC development with more complex, partially processed substrates tailored to specific applications.
Current steering topologies guide D/A converter design News & Analysis 9/18/2002 Post a comment Digital to analog converters form the heart of many communications and mixed-signal circuits. From the August issue of Planet Analog magazine, an AMI engineer shows how current-steering trees can weigh bits accurately, while minimizing crosstalk and silicon area.
Know where your data goes before you make USB go fast News & Analysis 9/18/2002 Post a comment USB has taken the computer peripheral world by storm. In a few short years, it has risen to be the dominant personal computer peripheral interface in almost every category, including printers, scanners, digital cameras, mice and keyboards. It is a "must have" interface for almost any peripheral. You want to add it to your design, so you pick the new 480 Mbits/s speed, right? Wrong, say Cypress engineers. Similar to any other engineering decision, there are tradeoffs involved. This article looks
Current limiting key to hot-swap circuit protection News & Analysis 9/18/2002 Post a comment Many approaches are available for protecting a system against electrostatic discharge (ESD), surge current, overcurrent, undervoltage, overvoltage, and other problems. Each accomplishes a specific set of tasks. Some protection circuits are associated with a particular industry or company, and others are linked to a specific standard such as UL, USB, IEEE, CSA, or IEC. This piece - a preview from the September 23rd PA magazine -looks at live insertion issues.
Solving the Power Management Conundrum News & Analysis 9/12/2002 Post a comment Designers looking to reduce consumption in 2.5G and 3G mobiles must improve power management in the analog and digital portions of a phone design. Here's some approaches on the horizon that might help.
Peering Into the CSIX Interface News & Analysis 9/11/2002 Post a comment The CSIX interface provides the promise of a common interface for the packet-processing portion of networking designs. Here's a look at the key CSIX elements and its impact on traffic manager/switch fabric designs.
Hitting the 10-Gbit Mark with SPI-4.2 News & Analysis 9/10/2002 Post a comment SPI-4.2 has become a pop star in the comm chip space. But to keep its stardom alive, designers must prove that this I/O can effectively handle 10-Gbit streams. And that's going to require proper configuration and usage.
SoC teams 8-bit core with FPGA News & Analysis 9/9/2002 Post a comment Most broadband solutions use high-end 32-bit processors coupled with large external memories and specialized media-access controllers (MACs), ASICs or FPGAs.
Understanding gain-and-load dependencies the key to successful rail-to-rail op amp use News & Analysis 9/4/2002 Post a comment Single-supply op amps with rail-to-rail operation are designed to support new-generation battery-powered portables. But their behavior can be quite different from that of conventional operational amplifiers with dual 15V rails. Read the data sheet performance curves carefully: They depict gain and load limitations, explains this Texas Instruments/Burr-Brown products veteran.
Battle-hardened veterans of the electronics industry have heard of the “connected car” so often that they assume it’s a done deal. But do we really know what it takes to get a car connected and what its future entails? Join EE Times editor Junko Yoshida as she moderates a panel of movers and shakers in the connected car business. Executives from Cisco, Siemens and NXP will share ideas, plans and hopes for connected cars and their future. After the first 30 minutes of the radio show, our listeners will have the opportunity to ask questions via live online chat.
