Abstract :
This paper provides a novel configuration to design a multi-scroll chaotic oscillator employing unity-gain cells (UGCs). The inclusion of multi-breakpoints to create a high-order negative nonlinear resistor (NR) is realized by the parallel combinations of basic cells. The breakpoints are controlled with resistors and tuning with level shifters. The multiscroll chaotic attractor has been optimized with plusmn1.5 V by using standard CMOS technology of 0.35 mum AMS. Hspice simulations performed in the state plane and in the time domain are shown.
