Ülkühan Güler, Salih Ergün · 2010
This paper presents an IC realization of a simple autonomous continuous-time chaotic oscillator, which realizes the double-scroll-like chaotic equation. Prototype ICs verifying the feasibility and the correct operation of the chaotic oscillator have been designed and fabricated by using HHNECs 0.25μm eFlash process with a supply voltage of 2.5V. Experimental results from a tested IC are given. Implemented circuit occupies 0.115mm2of area and dissipates 1.125mW of power. Furthermore, the presented chaotic oscillator is used as a core of random number generator, in order to show the usefulness of the circuit and also encourage its usage in the random number generation applications.
