这项工作提出了一种应用于安全通信领域的随机数生成器。为了获得真正不可预测的序列，使用了混沌系统。事实上，由于混沌系统对初始条件极其敏感，因此可以利用混沌系统来生成随机数。这项工作探索了这种可能性：特别挑选了一种基于流水线模数转换器的高效架构，以实现数字发生器的简单电路布置。根据仿真结果，该电路以20 Ms/s的速率提供均匀分布且统计独立的8位数字序列。该电路采用 0.8μm CMOS 技术实现，功耗为 50 mW。
This work proposes a random numbers generator for application in the field of secure communications. In order to get truly unpredictable sequences a chaotic system is used. Indeed, due to their extreme sensitivity to initial conditions, chaotic systems lend themselves to be exploited for generation of random numbers. This work explores this possibility: particularly an efficient architecture, based on a pipeline analog-to-digital converter, has been singled out, in order to realize a simple circuit arrangement of the number generator. According to simulation results, the circuit provides sequences of 8-b numbers that are uniformly distributed and statistically independent, at a rate of 20 Ms/s. The circuit is realized in 0.8-mum CMOS technology, and dissipates 50 mW.
