Keywords: chaotic neurons, Chua diode, sensitivity, modeling; hardware implementation, SPICE
Literature survey noteA Compilation of References on Chaotic Circuits
Xavier Peillon
Swiss Federal Institute of Technology – Lausanne, SwitzerlandThe use of chaotic systems asks for a large range of circuits, of various complexity and capabilities. Some of the recent papers proposing new circuits, or circuits in applications, or presenting analyses of chaotic circuits and related to them are listed below. This list is not intended to represent an exhaustive source. The main journals basing this compilation are IEEE Transactions on Circuits and Systems, International Journal of Chaos and Bifurcation, Applications on Chaos Theory, Int. J. Chaos Theory and Applications. Two Ph.D. theses were also included. Some of the titles are abridged in this list. Because the list below is intended to provide a guide and an overview without details, the readers should refer to the table of contents / index of the respective journals to find the needed details (journal issue, pages etc.) As a general remark, integrative papers in the recent literature are missing, unfortunately. Moreover, the textbooks and monographs in the field are not commenting in detail the circuitry available, each of them concentrating on a few solutions only (e.g., Chua circuit, or systems based on linear oscillators.) Another remark is that apparently, the number of papers devoted to new chaotic circuits is decreasing recent years, after a high in the years 1988-1993. Instead, the number of research papers on applications of chaotic circuits is increasing, mainly in the field of communications and data encryption.Although incomplete, we hope the list of references presented below may help the students and researchers to find out their way in a constantly growing but disperse literature on circuits exhibiting chaotic behavior.
