Chaotic characteristics in the iteration of logistic map tone-dimensional d
iscrete dynamic system) are simulated and analyzed. The circuit implementat
ion of a kind of chaotic amplifier model is based on the chaotic characteri
stics that chaos is sensitively dependent on its initial conditions, and th
e circuit simulation result is given using simulation program with integrat
ed circuit emphasis for personal computer (PSPICE), and is compared with li
near amplifier. Advantages and disadvantages of such a model are indicated.
