| Popis: | Chaotic oscillators have been implemented with a wide variety of discrete electronic devices and quite few realizations using integrated circuit te chnology. This article describes the synchronization of two chaotic oscillators already fabricated with complementary metal-oxide-semiconductor (CMOS) int egrated circuit technology of 0.5um and generating 3- and 5-scrolls. In order to attain the sy nchronization, we use a ma ster-slave topology with unidirectional coupling. Within this context, a system par ameter iterates until the corr elation coefficient computed between the chaotic signals generated by the master and slave systems approxim ates to unity. For the following parameter, its value depends on the standard deviations from the individual signals contrary to previous one. By combining those statistical relationships according to the number of system paramet ers, we can synchronize integrated chaotic oscillators. Theoretical model simulati ons of two chaotic oscillato rs generating 3- and 5-scrolls, and experimental results for two integr ated 3-scroll chaotic osc illators validate this approach. Stability and error analysis are also included. |
