Abstract
According to one embodiment, a programmable random bit source is disclosed. The programmable random bit source includes a latch having a data input, a bias input and a clock input. In addition, the programmable random bit source includes a programmable voltage source coupled to the bias input of the latch and a first oscillator coupled to the data input of the latch to output a first oscillating signal. Further, the programmable random bit source includes a second oscillator coupled to the clock input of the latch circuit to output a second oscillating signal having a frequency slower than a frequency of the first oscillating signal.
