RANDOM SIGNAL GENERATOR, RANDOM NUMBER GENERATOR INCLUDING THE SAME AND METHOD OF GENERATING A RANDOM NUMBER

摘要

A random signal generator, a random number generating including the random signal generator and a random number generating method are provided to generate a random signal and a random number insensitive to noise by adopting a differential self-bias structure. A random signal generator(100) includes a differential noise generating circuit(110), an amplification circuit(130) and a single-end amplifier(150). The differential noise generating circuit is self-biased and generates a differential noise signal. The amplification circuit amplifies the differential noise signal and outputs a differential amplification signal. The single-end amplifier outputs a random signal having irregular transition points based on the differential amplification signal.
