Abstract:
A random number generator includes: a variable frequency oscillator that includes: a selection circuit having multiple input terminals and an output terminal; a parallel circuit having an input terminal and multiple output terminals that are respectively connected to the input terminals of the selection circuit, the parallel circuit including one or more buffer circuits to be selected by the selection circuit; and an inverter circuit having a control terminal, the inverter circuit being connected to the input terminal of the parallel circuit and to the output terminal of the selection circuit; and a latch circuit connected to the variable frequency oscillator.
