Abstract: RC sine wave oscillation circuits with different structures were equivalent to LC parallel resonance circuits by changing the parameters of components，and the memristor with nonlinear characteristics was used to replace the Chua’s diode in Chua’s circuits，four equivalent Chua’s memristive chaotic circuits were designed， and the equivalent conditions were given theoretically. The simulation results show that the experimental results are consistent with the results of theoretical analysis and numerical calculation. The circuits are easy to adjust and have better robustness.

Key words: memristor, Chua’s circuit, LC resonance circuit, circuit simulation
