  • Frequency synthesis
    Patent number: 8581672
    Abstract: An apparatus including a spin torque oscillator configured to receive an input electric current and to produce a radio frequency output signal; and a tunable current source for providing an input electric current to the spin torque oscillator.
    Type: Grant
    Filed: May 14, 2010
    Date of Patent: November 12, 2013
    Assignee: Nokia Corporation
    Inventors: Pirjo Pasanen, Vladimir Ermolov, Markku Anttoni Oksanen, Martti Voutilainen, Eira Seppala
  • Apparatus and associated methods in relation to carbon nanotube networks
    Patent number: 8447715
    Abstract: In one or more embodiments described herein, there is provided an apparatus comprising a substrate, and a plurality of carbon nanotubes (semiconducting nano-elements) disposed and fixed with said substrate. The nanotubes are disposed and fixed on said substrate such that they define a carbon nanotube network substantially at the percolation threshold of the network. As the network is at the percolation threshold, this provides for one or more signal paths extending from an input region to an output region. The apparatus is configured to, upon receiving particular input signalling via the input region, provide particular predefined output signalling at the output via the one or more signal paths, the particular output signalling being predefined according to the one or more one signal paths.
