A random number generator using a single, slow, voltage controlled oscillator (10) which receives a noise input (14) and a plurality of high frequency ring oscillators (25-30). The ring oscillators are sampled under control of the slow oscillator. A circuit is used between the output of each of the ring oscillators and its respective D-type latch (31-36) to assure that the sampling is unbiased, that is, that there will be near even distribution of 1s and 0s in the random numbers.
