摘要：

A novel inductorless hyperchaos generator is proposed. The generator employs two identical linear current negative impedance converters (INICs) as the only active building blocks while nonlinearity is introduced via two generic signal diodes. The structure is truly inductorless as it is not based on active R-C emulation of passive inductors. A circuit implementation of the generator using current feedback op amps (CFOAs) is constructed and investigated both experimentally and using PSpice simulations. The generator is described by a fifth-order system of ordinary differential equations. Numerical simulation of the derived mathematical model is included and the positive Lyapunov exponents are estimated. (C) 1999 Elsevier Science Ltd. All rights reserved.
