Digging Out The Story -- One Case History
Sometimes it takes a little digging to pull a story out of a new product announcement. What's rewarding is when that digging turns up a story that illustrates how the design process actually works. Here's an example. A week ago, Linear Technology revealed its LTC3783...
EDA Alert: December 6, 2005
Viewpoint -- For FPGAs, Traditional Synthesis Falls Short, by Andy Haines, VP of Marketing, Synplicity Inc., Sunnyvale, Calif. FPGA technology has undergone quite a metamorphosis since it emerged on the scene in the 1980s, and the design technology that supports it has necessarily evolved as well...
Processing And Material Advances Steal The Spotlight At IEDM
Next week’s 51st IEEE International Electron Devices Meeting in Washington, D.C., provided a glimpse into the future of IC technology. Invited presentations from STMicroelectronics, Stanford University, and Toshiba Corp. are scheduled to open the conference by examining...
Dolby Laboratories' Legacy
Since the beginning of the Dolby licensing program in 1968, more than 1.8 billion consumer products incorporating Dolby technologies have been sold. More than 17,000 films were released with soundtracks encoded with Dolby technologies. Over 79,000 of the processors needed to decode those soundtracks have been sold to theaters. The company is headquartered in San Francisco, with European headquarters in England; film and broadcast support offices in New York and Los Angeles; and...
Power and Analog Make Successful Consumer Electronics
Conventional wisdom in consumer electronics, driven by Moore's law, calls for increasing functionality on single SoCs. But the laws of physics (heat, current leakage, crosstalk, etc.) have all but eliminated Moore's law as a gating factor for functional integration in consumer electronics. Modern microprocessors drain batteries like the engine of a Hummer drains...
The Design of CMOS Radio-Frequency Integrated Circuits, Second Edition
Since the days of pioneers like Marconi and Armstrong, radio has fascinated countless numbers of engineers. Wireless technology has evolved from the days of bulky, power-hungry vacuum tubes to today’s tiny, battery-powered portable...
Getting Reacquainted With Radio
You would probably guess that an editor like me who covers wireless and all manner of communications subjects would be a ham. I have, in fact, been involved in amateur radio for most of my natural life. My first ticket was a novice license (WN5TOM) when I was 13 years old...
