How true random numbers occur with environmental resistance

摘要

A true random number generator (TRNG) system includes a first noise source configured to generate first analog noise signals and a second noise source identical to the first noise source and configured to generate second analog noise signals. The analog comparator receives first analog noise signals and second analog noise signals as input and outputs digital signals based on comparisons of the first analog noise signals and the second analog noise signals. The conversion system receives the digital signals and generates a random bit stream signal from the digital signals. The output pin is coupled to receive a random bit stream signal from the conversion system.
