A random bit stream generator and method including a regulated current source for generating a noise signal, an amplifier coupled to the regulated source for producing an amplified noise signal, a filter coupled to the amplifier for averaging the random bit stream and producing a feedback input, a comparator coupled to the amplifier and the filter for receiving the amplified noise signal and the feedback input and producing a digital signal, a flip-flop coupled to the comparator for receiving the digital signal and for producing the random bit stream, and quick start circuitry coupled to the amplifier, the comparator, and the flip flip for ensuring randomness in the random bit stream from generator start up.
