  • Apparatus and method for generating random number
    Patent number: 8443022
    Abstract: A random number generating apparatus and method for generating a metastable state signal by using logic gates include a metastable state generating unit generating and outputting a metastable state signal; an amplifying unit receiving the metastable state signal from the metastable state generating unit, amplifying the received metastable state signal, and outputting the amplified metastable state signal; and a sampling unit receiving the amplified metastable state signal and a sampling clock, and sampling and outputting the amplified metastable state signal according to the sampling clock.
    Type: Grant
