James D. Meindl, the director of the Microelectronics Research Center at the Georgia Institute of Technology, says there is a limit to the miniaturization of the electronic components we use in computers and other products. The limit is absolute temperature. Meindl and collaborator Jeffrey A. Davis came to their conclusion by studying the limit two ways. First, they studied the minimum energy required for producing a distinguishable binary transition. They also examined the minimum energy required for sending the resulting signal along a communications channel. The limit for both studies was the same and expressed as E(min) = (In2)kT. In the equation, T is absolute temperature, k is Boltzmann's constant, and In2 is the natural log of two. Although this fundamental limit provides a theoretical stopping point for electronics designers, Meindl says we'll never get close to it because electronic signals move through interconnects no faster than the speed of light and because quantum mechanics theory introduces uncertainties. So, what's next for microelectronics?. No one knows for certain, but Meindl says that's what his nanotechnology research is trying to answer.
Halloween isn’t just a time for creative costumes. Thanks to the element14 online design community, the holiday this year also brings us a number of creative electronic device design ideas aimed at making your Halloween party a unique experience.
On April 15, 2010, President Barack Obama gave a major speech at the Kennedy Space Center in Florida, announcing that the US would send astronauts to Mars by the mid-2030s. But in order to do so, NASA would first need to ramp up its capabilities through missions directed toward "a series of increasingly demanding targets," i.e. asteroids.
