The simple autonomous jerk circuit of [J. Kengne, Z. T. Njitacke, A. N. Nguomkam, M. T. Fouodji and H. B. Fotsin, Coexistence of multiple attractors and crisis route to chaos in a novel chaotic jerk circuit, Int. J. Bifurcation Chaos Appl. Sci. Eng.\u00a026 (2016) 1650081] is used as the prototype. In contrast to current approaches where the diodes are assumed to be identical (and thus a perfect symmetric circuit), we examine the more realistic situation where the diodes have different electrical properties in spite of unavoidable scattering of parameters. In this case, the nonlinear component formed by the diodes pair displays an asymmetric current\u2013voltage characteristic which induces asymmetry of the whole circuit. The model is described by a continuous-time 3D autonomous system (ODEs) with exponential nonlinearities. We examine the chaos mechanism with respect to system parameters both in the symmetric and asymmetric modes of operation by using bifurcation diagrams and phase space trajectory plots as the main indicators. Period doubling route to chaos, merging crisis, and multiple coexisting (i.e., two, four, or six) mutually symmetric attractors are reported in the symmetric mode of oscillation. In the asymmetric mode, several unusual nonlinear behaviors arise such as coexisting bifurcations, hysteresis, asymmetric double-band chaotic attractor, crisis, and coexisting multiple (i.e., two, three, four, or five) asymmetric attractors for some suitable ranges of parameters. Theoretical analyses and circuit experiments show a very good agreement. The results obtained in this work let us conjecture that chaotic circuits with antiparallel diodes pair are capable of much more complex dynamics than what is reported in the current literature and thus should be reconsidered accordingly in spite of the approach followed in this work. <\/jats:p>","DOI":"10.1142\/s0218126621500778","type":"journal-article","created":{"date-parts":[[2020,7,22]],"date-time":"2020-07-22T16:38:28Z","timestamp":1595435908000},"page":"2150077","source":"Crossref","is-referenced-by-count":4,"title":["Asymmetry-Induced Dynamics for a Class of Diode-Based Chaotic Circuits: A Case Study"],"prefix":"10.1142","volume":"30","author":[{"given":"L\u00e9andre Kamdjeu","family":"Kengne","sequence":"first","affiliation":[{"name":"Unit\u00e9 de Recherche de Mati\u00e8re Condens\u00e9e, d\u2019Electronique et de Traitement de Signal (UR-MACETS), Department of Physics, University of Dschang, P.O.
