ABSTRACT:
A random number generator (RNG) uses an edge-triggered D-type flip-flop with a high frequency square wave having an approximately 50 percent duty cycle connected to a data input terminal and a low frequency square wave connected to a clock input terminal, a five-state counter, five two-input AND gates, five exclusive-OR gates, and five shift registers. An essentially truly random number is generated at the RNG output terminals. Probability biases due to both variations in the 50 percent duty cycle of the data waveform and small amounts of cycle-to-cycle jitter of the clock waveform are effectively removed.
