A digital true random number generator circuit, comprising a linear
feedback shift register having an input and an output, a system clock
having a system clock frequency value for driving the shift register, and
a plurality of free running oscillators operatively connected to the input
of the shift register. The oscillators and the system clock having
different oscillation frequency values, the greatest common divisor of
which having the value one, thereby avoiding locking of the oscillators
and the system clock.
