A REALIZATION of SC-CNN-BASED CIRCUIT USING FTFN

On the other hand, since its definition by Chua&Yang [2], Cellular Neural Networks (CNNs) received a great deal of interest. Although many of these applications were proposed for numerous disciplines like artificial life and image processing [3], some have been adapted for chaos [4-7]. In one of these applications, Arena et al. realized unfolded Chua’s circuit using the connection of three simple generalized CNN cells and called this network structure as State-Controlled CNN (SC-CNN) [4]. The proposed SC-CNN-based circuit is realized by using voltage-mode op amp (VOA) as an active element. Afterwards this SC-CNN based circuit has been used in the chaos-based secure communication systems as a chaos generator [5,6].
