Novel random number generation methods and novel random number generators with a dual architecture comprising a fast oscillator and a noise source are presented. Numerical and experimental results presented in this innovation not only verify the feasibility of the proposed circuits, but also encourage their use as the core of a high-performance IC TRNG as well. The proposed innovation is an enhanced design where dual architecture is exploited in order to increase the throughput and to maximize the statistical quality of the output sequence and to be robust against external interference, parameter variations and attacks aimed to force throughput. In conclusion, we can deduce that the proposed circuits can be integrated on today process at GHz range and the use of the proposed RNGs is very promising in generating random numbers with very high throughput.
