In 1999, Intel fellow Fred Pollack gave a talk “New Microarchitecture Challenges in the Coming Generations of CMOS Process Technologies” in which he presented the now classic graph predicting how (if the trend continued) rising power consumption for processors built in successive generations of CMOS would push CPU power density to the level of the sun’s surface in another decade. Of course, that didn’t happen. Pollack’s graph plotted power density versus process geometry with CPU generations identified on the curve (this graph is available on slide 8 of http://research.ac.upc.edu/HPCseminar/SEM9900/Pollack1.pdf). Others took this data and ran with it when discussing power management challenges for power semiconductor and VRM designers. The illustrated version linked to here, which substitutes years for process geometries on the X axis, appears on the kurzweilai.net site. view »

While working as an RF system and circuit design engineer, Kirt Blattenberger began using some AOL web space to assemble formulas and reference materials he needed for work. However, he soon discovered that many others were interested in these same materials. Over time, he continued to add content and created the RF Café website, which now houses a fascinating smorgasbord of information for RF engineers. However, the site also contains many useful listings on power electronics topics. From the home page, locate the listings for Engineering Resources, and click on Tech Resources. From there check out links such as Power Supply Design, Transformer Design, Inductor Design, Filter Design Resources, Battery Design, and EMC/EMI/RFI Resources. view »
