      A modulator/demodulator CMOS IC for chaotic encryption of audio  [Presentation]

      Delgado Restituto, Manuel; Rodríguez Vázquez, Ángel Benito; Liñán Cembrano, M. (Institute of Electrical and Electronics Engineers, 1995)
      This paper reports the first experimental verification of chaotic encryption of audio signals using integrated circuits. It is based on a gm-Cmodu¬ lator/demodulator analog CMOS IC that implements a 3rd-order nonlinear ...
