True random number generator circuit for comparing thermal noises of equal resistors

Номер: CN0101751240A
Автор: YU HUIHONG, HUIHONG YU
Принадлежит:

The invention is used for generating a true random number sequence, the main principle is based on the comparison of thermal noises of two equal resistors so as to enlarge variances of thermal noise functions and reduce the design difficult, namely the requirements on subsequent circuits. A comparator is in a state of open-loop application and is more easily stable than an operation amplifier. At the same time, the structure can flexibly control the velocity of the random number sequence through an external clock.
