Cell phones use modern modulation schemes that require linear amplification of the RF signal. A typical way to achieve this linearity is to burn more power in the output stage. This approach reduces efficiency, ....
In a conventional diode-rectified flyback converter, the output diode rectifier is a substantial power-loss contributor. The average current in the output diode is equal to the dc output current, and ....
Advances in server-processing power have coupled with increasing demands on workloads to drive up data-center power consumption in the United States. Currently, data centers, or server “farms,” account ....
Memory devices are evolving to match the needs of applications that are in continuous demand, such as high-performance communications, networking, and DSP systems. Specialized memory products that optimize ....
I am a firm believer in the theory that science fiction not only forecasts, but also shapes the future. Those of us who grew up watching The Jetsons may well remember the scenes of the family watching ....
The line between toys, games, and “real-world” applications is blurring. Technologies that originally found use in serious real-world applications continue to find their way into the much-larger-volume ....
For years, video has been an integral part of specialized industrial systems, such as surveillance and factory inspection. However, it has only recently become a viable addition to a range of embedded ....
Steady streams of RF energy constantly engulf your electronic system. Some of this energy comes from the accidental byproduct of a system; other RF sources, such as radios and radar, intentionally radiate ....
The HB LED (high-brightness light-emitting diode) continues to increase in power: For example, Cree currently offers devices capable of producing 88 lm/W, and plans call for the emergence of 100-lm/W ....
As the mercury drops below freezing, it’s nice to be able to focus our attention on something hot. For some of you, this scenario might mean lounging on a sunny beach in Hawaii, piña colada in hand. For ....
