| 摘 要： | 提出了由一个晶体管、两个电容和两个电阻组成的非自主混沌电路，混沌行为基于积分干扰以及双极性晶体管两极对电容正一反向的充电，调节振荡器的频率得到了完整的混沌仿真波形，并通过PSpice软件计算了李雅诺夫指数，证实了混沌特性。

| Abstract: | A nonautonomous chaotic circuit based on one transistor, two capacitors, and two resistors is described. The mechanism behind the chaotic performance is based on ＂disturbance of integration＂. The forward part and the reverse part of bipolar transistor are ＂fighting＂ about the charging of a capacitor. By varying the frequency of the oscillator, chaotic behavior is perfectly emulated. The Lyapunov exponents have been calculated from PSpice software, thus confirming the chaotic nature. |
