Dependent claims

A random number generator, comprising:

a control word providing circuit, configured to generate a plurality of control words in response to a first rule, wherein integer portions of the plurality of control words are coprime;
a pulse generating circuit, connected to the control word providing circuit and configured to output a plurality of pulse signals in response to the plurality of control words, wherein each of the pulse signals comprises a first frequency signal and a second frequency signal, wherein an occurrence probability of the first frequency signal in the pulse signal is controlled by a control word corresponding to the first frequency signal, and an occurrence probability of the second frequency signal in the pulse signal is controlled by a control word corresponding to the second frequency signal;
and
a random number generating circuit, connected to the pulse generating circuit and configured to generate a random number sequence by performing a logical operation on the plurality of pulse signals.
