One analyst takes on the PM market Power DesignLine Blog 9/30/2009 Post a comment Global sales of digital power semiconductors are set to increase to $821 million in 2013, up from $127 million in 2008, according to iSuppli Corp. The most rapid growth will be in DCPs.
Green power in the future Power DesignLine Blog 9/18/2009 Post a comment Sharp Microelectronics reported its first loss ever this year so the company is investing in a future "green" to ensure it keeps its competitive edge.
Ban the power for BANs Power DesignLine Blog 9/9/2009 Post a comment Qualcomm described a new algorithm to lower the power of body area networks at a recent conference. The medical industry needs that to have sensors work 24/7 in regular living conditions without wireless packets getting lost.
Managing waves and thoughts Power DesignLine Blog 9/2/2009 Post a comment Bin He can point to a spot on the brain that gave off a sub-microvolt signal corresponding to a thought. The question now is can thoughts be managed with the same techniques used to manage power?
Fishy power requirements Power DesignLine Blog 8/26/2009 Post a comment MIT researchers have displayed prototype robotic fish that have just ten moving parts, including a single motor. Some prototypes have survived in the lab for four years of constant underwater tests without a leak.
Watch out for nuclear fusion research Power DesignLine Blog 8/19/2009 Post a comment Researchers are adapting a new plasma-based lithography that generates "extreme ultraviolet" light with a wavelength of 13.5 nanometers using the same methods applied in fusion-energy research. That's another challenge for future power management of chips.
