| 发明名称 | Apparatus for generating random number | ||
| 摘要 | An apparatus configured to generate random numbers is provided, the apparatus having high entropy and being capable of a reduced chip size. The apparatus includes a plurality of metastable state generation units configured to generate a metastable state signal, a plurality of amplification units configured to amplify the metastable state signal, a connection signal generation unit configured to generate a first connection signal, and a first commutation unit configured to connect at least one metastable state generation unit to at least one amplification unit according to the first connection signal. For example, the number of metastable state generation units and amplification units necessary to achieve are threshold number of commutation connections can be greatly reduced as compared to conventional apparatuses for generating random numbers. | ||
