A chaotic integrated circuit is designed and fabricated using a 0.35µm CMOS process. The circuit iterates an N-shaped transfer function using a small analog neural network. One of the advantages of the proposed circuit is its small circuit area with only 13MOS transistors. The circuit generates both an analog and a digital signal that can be used to create true random bit sequences.
