A random signal generator circuit includes a thermal noise generator circuit and a self-biased inverter having an input coupled to the thermal noise generator circuit and to a feedback resistor coupled to an output of the self-biased inverter, the self-biased inverter configured to produce a sensed noise signal at the output responsive to thermal noise generated by the thermal noise generator circuit. An amplifier circuit is coupled to the output of the self-biased inverter and configured to amplify the sensed noise signal to produce a saturated random signal. The saturate random signal may be sampled, e.g., with a flip-flop, to generate a random binary signal that may be used for random number generation.
