Abstract
Various embodiments are described that relate to random number generation. When a desire arises for a random number a circuit can be completed with a reverse biased semiconductor junction element. When the circuit is completed an analog voltage spike can be produced that is random due to properties of the reverse biased semiconductor-junction element. This analog voltage spike can be converted into a digital value that serves as the random number. The digital value can be outputted and used as the random number.
