A Simple Nonautonomous Chaotic Spiking Circuit with a Refractory Threshold Yoshifumi KOBAYASHI Hidehiro NAKANO Toshimichi SAITO Publication IEICE TRANSACTIONS on Fundamentals of Electronics, Communications and Computer Sciences Vol.E88-A No.9 pp.2464-2467 Publication Date: 2005/09/01 Online ISSN: DOI: 10.1093/ietfec/e88-a.9.2464 Print ISSN: 0916-8508 Type of Manuscript: LETTER Category: Nonlinear Problems Keyword: chaos, bifurcation, spiking neurons, pulse-coupled neural networks, Full Text: PDF(286.2KB)>>
Summary: This letter studies a simple nonautonomous chaotic circuit constructed by adding an impulsive switch to the RCL circuit. The switch operation depends on time and on state variable through a refractory threshold. The circuit exhibits various chaotic attractors, periodic attractors and related bifurcation phenomena. The dynamics can be analyzed using 1-D return map focusing on the time-dependent switching moments. Using a simple test circuit model typical phenomena are verified in PSPICE simulations. | ||||||||||
