Abstract :
Reports a working microelectronic chip implementation of Chua´s circuit. This chip has been designed and fabricated by using a 2 μm CMOS technology, with the circuit itself occupying a silicon area of 2.5mm×2.8mm. The chip needs to be powered with a single 9V battery, is autonomous, and generates chaotic signals from the three state variables of Chua´s circuit. The proper operation of this chip has been confirmed by experimental reproduction of bifurcation and chaotic phenomena. This microelectronic design of Chua´s circuit can be employed as a basic component in the VLSI synthesis of complex circuits making use of chaotic signals, including a class of cellular neural networks and secure communication systems
