A true Random Number Generator using RTN noise and a sigma delta converter

The design of a true Bernoulli Random Number Generator (RNG) source with a true probability p = 0.5 is a challenging problem. In this work, we present a novel design of a True RNG (TRNG) that achieves a true E(p(n)) = 0.5. The architecture is based on the perturbation of a Sigma-Delta modulator using random telegraph noise (RTN).
