A generation method of the integrated circuit random sequence number

For edge effect, ion inpouring and surface state effect and change of current carrier mobility ratio, mismatching of apparatuses can be generated, high-gain amplification circuit detects the mismatching of the apparatuses and transforms into digital level which is corresponding with it, because randomicity of the mismatching between these apparatuses is strong, so using many amplification circuit units can realize the generation of multi-bit random sequence number.
