The Smallest Transistor-Based Nonautonomous Chaotic Circuit
Yang Zhi-min · Journal of Xingtai Polytechnic College · 2007
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.
