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

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.
Heading out onto the fiber
Design How-To  
9/4/2002   Post a comment
Optical communications quenches the industry's thirst for ever greater bandwidths, but placing information onto fiber is not without its challenges. This paper, originally published in a sister publication (Microwave Engineering) looks at some of the modeling issues associated with components and signal conditioning stages required for Electro-Optic Transmission.
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.
DSP-Enabled Efficient Motion Estimation for Mobile MPEG-4 Video Encoding
Design How-To  
9/4/2002   Post a comment
Efficient motion estimation is vital for video encoding in mobile devices. J. Geoffrey Chase and Christopher Pretty of University of Canterbury, New Zealand present a highly efficient four-step search algorithm for 16-bit DSPs and the impact of dynamic reconfiguration of the DSP's data path.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
