| # RNG CHAOS SCROLL |
| |
| Chaotic systems are deterministic and bounded in phase space, |
| but they have positive Lyapunov exponents leading to completely |
| divergent signals even for very small perturbations in initial conditions. |
| Therefore, chaotic oscillators are frequently employed in Random Number Generator(RNG) |
| applications where repeatable, secure and high-performance entropy sources are required. |
| Chaotic oscillators can be implemented in either analog or digital circuits, |
| but chaotic oscillators implemented in the digital domain are preferable for ease of |
| integration to digital systems. In this study, a digital RNG based on chaotic oscillators |
| was implemented using the SKY130 process node. |
