ABSTRACT
This chapter reviews different scenarios where chaotic Integrated Circuits (ICs) might play a role. Then, it outlines general considerations pertaining to the implementation of both ordinary differential equation (ODE)- and fìnite-difference equation (FDE)-based chaotic ICs. It has been demonstrates that the design of electronic circuits with customized, controllable chaotic behaviour is of interest for applications such as neural computation, instrumentation, analog signal processing and control, communication, and so on. The use of chaos in communication systems defines one of the most appealing applications of chaotic signals developed. Chaotic signals present some particular features which make them interesting to convey information. Charge injection errors in switched-current circuits include dummy switch compensation, fully differential architectures, algorithmic cancellation and adaptive timing of the clock signals. Delays are realized by using sample-and-hold structures, which in the case of switched- capacitors employ opamps, capacitors and analog switches.
