Abstract :
We design and simulate an improved wideband chaotic Colpitts oscillator based on micro-strip technology. The numerical and circuit simulation results are presented in order to verify the performance of the developed oscillator. In addition, we propose the synchronization model between two identical improved chaotic Colpitts oscillators coupled by a resistor. The chaotic synchronization, one of the most important requirements for chaotic communication systems, is validated by numerical and circuit simulation results. And synchronization thresholds are also estimated.
