Abstract: A chaotic circuit is designed using current feedback operational amplifiers (CFOAs).The circuit consists of three integrators,two nonlinear circuits,and one subtractor.The circuit can generate grid multi-scroll chaotic attractors.The central frequency of the circuit is higher with fewer active components and simpler circuit construction for the good frequency characteristic and port characteristic of the CFOA.The circuit simulation results are in agreement with the numeral simulation results.Simulation results show that the designed circuit is correct.

Key words: grid multi-scroll chaotic attractors, current feedback operational amplifier, circuit implementation
