Abstract
Nowadays, chaotic systems are very interesting topics for engineers, physicists and mathematicians because most real physical systems are inherently non-linear in nature. The first electronic implementations of autonomous chaotic oscillators were developed using operational amplifiers and diodes, different references detail implementations of chaotic circuits and systems using analog integrated circuit technology, discrete devices such as FPGA (Field programmable gate arrays), microcontrollers, etc. However, analog implementations suffer the problem of sensitivity of analog component values and digital implementations suffer the problem of degradation due to the reduced number of bits to perform computer arithmetic operations. The systems of differential equations that model the chaotic oscillators require integrators that can be implemented with FPAA's (Field programmable analogue array), in this work electronic implementations are developed that are measured in laboratory conditions to observe experimental chaotic attractors, which will be used in the implementation of random number generators and secure communication systems for image encryption.
