Abstract:
The paper present an ADS (Advanced Design System) implementation of a new and simple UWB (Ultra Wide Band) chaotic generator based on memristor switching model. The simplest electronic circuit to generate UWB chaotic signals is proposed, and chaotic behavior is proved using several test cases such as period-doubling illustration, lyapunov exponent's computation, chaotic attractors and bifurcation diagrams plots. This paper provides the ADS implementation of this memristor based UWB chaotic generator and compares implementation results with Matlab simulations. The same chaotic system working at higher frequency is capable of generating different sequences with good correlation properties and ultra wide band spectrum. These properties make our generator well suited for UWB communications based on ultra-short duration pulses which yield ultra-wide bandwidth signals characterized by extremely low power spectral densities.
