Abstract :
In this paper, we develop an improved chaotic Colpitts oscillator applied to ultra wide band wireless communication system. We design, simulate and implement the improved chaotic Colpitts oscillator using Philip´s wideband transistor BJT BFG425W. The numerical simulation using Matlab and circuit simulation using Advanced Design System (ADS) are also presented. The oscillator is designed based on micro-strip substrate and the simulation result of the layout approves the possibility for UWB wireless communication applications.
