Novel random number generation methods and novel random number generators based on continuous-time chaotic oscillators with dual oscillator architecture are presented. Numerical and experimental results not only verify the feasibility of the proposed circuits, but also encourage their use as a high-performance IC TRNG. In comparison with RNG's based on discrete-time chaotic maps, amplification of a noise source and jittered oscillator sampling, which are advantageous in the sense that true random behavior can be mathematically proven thanks to an analytical model that has been developed, it is seen that RNG's based on continuous-time' chaotic oscillators can offer much higher and constant data rated without post-processing. The proposed innovation increases the throughput, maximizes the statistical quality of the output sequence and is robust against external interference, parameter variations and attacks aimed to force throughout. The proposed circuits can be integrated on today process at GHz range.
