This paper reports the first experimental verification of chaotic encryption of audio signals using integrated circuits. It is based on a gm-Cmodu¬ lator/demodulator analog CMOS IC that implements a 3rd-order nonlinear differ¬ ential equation. This has been fabricated in 2.4|j,m double-poly technology and includes on-chip tuning circuitry based...
