Random numbers play an important role in the fields such as cryptography,simulation and IC testing.The random numbers used in cryptography are often required to hold the unpredictable characteristic.Based on chaos,and using switched capacitor circuits,a random number generator(RNG)is designed and realized with integrated circuit in this paper.The testing results show that the sequence generated by this RNG is unpredictable,and can fit in with the requirement in cryptography.
