Abstract :
Recently, much attention has been given to the generation and synchronization of chaos for signal encryption. Some implementations have been reported using OTA and conventional operational amplifiers. Here we present a current-mode implementation using simple current integrators, current mirrors, and a current hysteresis element. The current-mode technique allows for fewer components, and thus, a more efficient monolithic implementation
