Abstract: A physical random number generator operates to generate a true random bit sequence while a linear feedback shift register and a clock collectively operate to provide a plurality of feedback random bit sequences. In operation, the linear feedback shift register periodically latches the feedback random bit sequences in response to a clock signal having a predetermined operating frequency from the clock. In latching the feedback random bit sequences, the linear feedback shift register includes a plurality of bi-stable latches for linearly shifting a mixed random bit sequence outputted by an XOR gate, which is combined with the true random bit sequence. A decimator receives a feedback random bit sequence and provides an output random bit sequence that is representative of a selective outputting of the feedback random bit sequence.
