Random signal generator for securization of data communications, has amplifier with single output for generating random signal based on amplified differential signals, where random signal has irregular transition instants

摘要

The generator (100) has an amplification circuit (130) amplifying a differential noise signal delivered by an output of a differential noise generation circuit (110) to generate amplified differential signals. An amplifier (150) has single output for generating a random signal based on the amplified differential signals, where the random signal has irregular transition instants. A generation circuit includes a pair of resistors (RN3, RN4) with an autopolarisation mounted between a pair of input nodes and a pair of output nodes.
