Abstract Through analyzing the nature of the evolution of the deterministic chaos and partitioning its state space, a deterministic chaotic system can be turned into an ergodic information source which could be used to design a Random Number Generator(RNG). The characteristics of a chaotic piecewise-linear map are also analyzed, for instance, chaotic attractor and point attractor, source entropy and redundancy, as well as the distribution of the sequence generated by the map. Further, the map is implemented in TSMC O.25um CMOS mixed-signal process utilizing switched capacitor circuit techniques. The test results indicate very good performance in anti-jamming.
