Abstract
A circuit and a method for generating a random number are provided. The circuit for generating the random number includes an analog-to-digital converter and a controller. The analog-to-digital converter sequentially generates a plurality of digital data in response to an analog signal. The controller utilizes an estimation procedure to sequentially analyze a variation trend of the plurality of digital data in a time sequence or extract components of the plurality of digital data within a preset frequency band. In addition, the controller generates a true random number based on a result of the estimation procedure.
