Abstract: This paper introduces three types of stimulated inductances,and the application to chaotic synchronization circuitsFinally,comparing their characteristics wi th each otherAccording to simulation, stimulated inductances are verified tha t real inductances can be replaced by them in chaotic synchronization, but have no influence on circuit′s characteristicHence, stimulated inductances are no t only used for integration,but also have advantages of solving the PRoblem of the sensitivity to original value of chaotic synchronization circuit, which has a better application in future
