ABSTRACT:
A random-bit sequence generator includes a biasing circuit, a source of a noisy voltage signal biased by the biasing circuit, an amplification stage generating an amplified signal representative of the sole non-zero-frequency (AC) component of the noisy voltage signal and an output stage electrically in cascade to the amplification stage that generates a random bit sequence in function of the amplified signal. The generator also filters the undesired low-frequency disturbance components because the amplification stage comprises an input low-pass filter that feeds the zero- (DC) component of the noisy voltage signal to one of the inputs of a differential amplifier, to another input of which is fed the non-filtered noisy voltage signal.
