New wireless chip uses ten times less power

Posted on Wednesday, April 26 2006 @ 09:30:38 CEST by

DailyTech writes researchers at the University of Rochester have developed a wireless chip design that allows devices like cell phones or Wi-Fi products to use much less power. According to their report the chip only uses one tenth of the power required by traditional designs.
Hui Wu, an EE and CE professor at the University of Rochester, has improved upon injection locked frequency divider (ILFD) circuit design. While the low-power benefits of ILFD designs have been known for quite some time by researchers and wireless chip manufacturers, two hurdles have prevented the technology from being adopted by the industry. The first issue was the inability of the circuit design to handle a wide range of frequencies. Wu and Ali Hajimiri, an associate professor of EE at Caltech, solved that issue back in 2001. The second hurdle was the inability to offer a high enough resolution within a given frequency range.
