Abstract The requirement of high quality random numbers grows day by day,’ so true random number generator takes great attentions; And the appearance and development of system on a chip needs the realization of on-chip random number generator. Considering the two facts, this paper comes up with a new method of random number generator based on the noise source of PLL.The method can provide a good property: true randomness and easy realization and system integration.
