WebAbstract—Thermal jitter (phase noise) from a free-running ring oscillator is a common, easily implementable physical ran-domness source in True Random Number Generators (TRNGs). We show how to evaluate entropy, autocorrelation, and bit pattern distributions of ring oscillator noise sources, even with low jitter levels or some bias. WebRing-based voltage-controlled oscillators (VCO) are well-suited for integration since they require no external components. While their intrinsic phase noise is relatively high …
