I have been watching the developments in nanotechnology as a potential enabler for the new generation of wireless systems. I was initally captivated by the idea of creating a vaccum tube on a wafer using carbon nano tubes. While traditional vaccum tubes are inefficient, they have very high gains which are difficult to realize in solid state electronics. I think analog signal processing is bound to come back…

In any case, I think this paper is a significant stepping stone towards this direction. The paper is here. They even have a demo video (and a nice taste for Irish music).
