摘要
提出了一种基于混沌的随机源电路 ,通过利用电容上电荷的再分配 ,实现了一个离散混沌系统 .该电路在0 .8μm CMOS工艺下流片成功 ,核心面积小于 4 2 0 0 μm2 ,功耗小于 1m W,优于目前已有的几种实现方法 .
A chaotic circuit for truly random number generation is proposed.The chaotic system used in the circuit is implemented with the charge redistribution of capacitors.The prototype circuit is fabricated with a standard 0.8μm CMOS techno- logy process.The size of core is less than 4200μm2 and the power consumption is less than 1mW,which are better than that from most of present methods.
