Abstract
A random number generator may include a first meta-stable inverter having an input terminal and an output terminal connected to each other and configured to generate a meta-stable voltage, an amplifier configured to amplify the meta-stable voltage, control circuitry configured to adjust a threshold voltage of the meta-stable voltage, and a sampler configured to generate a random number based on sampling the meta-stable voltage. The random number generator may be configured to be operated according to different modes of operation of a plurality of modes of operation. The amplifier may be a second meta-stable inverter configured to amplify the meta-stable voltage or include an input terminal and an output terminal that are connected to each other based on the random number generator being operated according to a first mode of operation or a second mode of operation, respectively, of the plurality of modes of operation.
