The semiconductor industry's return to profitability probably will be short-lived, as a coming slowdown in consumer and IT upgrade spending are conspiring with capacity additions to create another recession in 2005, according to Semico analyst Jim Feldhan. From Phoenix, Brian Fuller reports.
Loop design sometimes compensates for lower-quality switchers
Blog  
3/16/2004   Post a comment
Sanjaya Maniktala is back with a new installment of his popular power supply design column. The question he asks is how to make up for the erratic quality of the 3842 and 3844 switching power supply controllers now on the market? An adjustment of the RC components in the hysterysis loop allowed a power supply company to safely utilize the batch lot of jittery components they were stuck with - some 50,000 of them.

High-speed line cards reemerge
News & Analysis  
3/3/2004   Post a comment
When the telecommunications sector crashed more than three years ago, development of 10- and 40-Gbit/second line cards was dropped in favor of slower designs that provided a migration path from existing OC-3 and OC-12 equipment to OC-48-class speeds, writes Rob Keenan in his introduction to EE Times' InFocus article section. But with OC-48 now proliferating and Gigabit Ethernet and 10-Gbit Ethernet starting to gain hold in metro markets, designers are once again building high-speed line cards th
