  • Random number generator including entropy source
    Patent number: 10656916
    Abstract: Embodiments include apparatuses, methods, and systems for a random number generator that includes an entropy source. The entropy source may be coupled to a deterministic feedback circuit and a stochastic feedback circuit. The deterministic feedback circuit may include detection logic to detect when a bit of the output signal of the entropy source has registered, a pre-delay feedback path to cause the entropy source to power off responsive to the detection, and a post-delay feedback path to cause the entropy source to power on, after the entropy source is powered off, to generate a second bit of the output signal. The post-delay feedback path may include one or more delay cells that are bypassed by the pre-delay feedback path. Other circuits and techniques related to random number generators are also described. Further embodiments may be described and/or claimed.
