Summary:The present description concerns a random number generation circuit (2) of correlated sampling ring oscillator type comprising: two identical ring oscillators (RO1, R02) implemented in CMOS-on-FDSOI technology; a circuit (104) sampling and storing an output (O1) of one of the two oscillators (RO1) at a frequency of the other one of the two oscillators (R02) and delivering a corresponding binary signal (Beat); and a circuit (200) controlling back gates of PMOS and NMOS transistors of at least one delay element of at least one of the two oscillators (RO1, R02) based on a period difference between the two oscillators (RO1, R02).
