摘　　要：为了简化蔡氏二极管的设计,提出了一种分段线性正电阻的设计方法。将设计的分段线性正电阻转换成分段线性负电阻,该分段线性负电阻用于设计新的蔡氏电路,通过EWB仿真和硬件电路测试表明新的蔡氏电路能有效地产生混沌行为。无论是从产生的混沌行为还是从电路的结构来看,均具有现有蔡氏电路所不具备的一些优点,结果表明电路设计是有效的。To simplify design of the Chua＇s diode,a design method based on piecewise-linear positive resistance is proposed. The design of piecewise-linear positive resistance into piecewise-linear negative resistance,design of new Chua＇s circuit based on the piecewise-linear negative resistance,EWB simulation and hardware circuit testing show that Chua＇s circuit can effectively generate chaotic behavior. Both the chaotic behaviors or structure of circuit occupy the advantages which are not existing in the Chua＇s circuits,the results show the design of this circuit is effective.
