Abstract
An apparatus comprises a noisy bias voltage generator circuit, a random seed generator circuit, and a random series generator circuit. The noisy bias voltage generator circuit may be configured to generate a plurality of noisy bias voltages in response to a plurality of input voltage signals and a first bias current signal. The random seed generator circuit may be configured to generate a random seed in response to the plurality of noisy bias voltages and a second bias current signal. The random series generator circuit may be configured to generate a series of true random bits in response to the random seed and a clock signal.
