Abstract
Random number generator (GL) comprising adjustable speed ring oscillators (GPRS, GPRS'), which have outputs (o-GPRS, o-GPRS′) connected to inputs (i-UM, i-UM) of a metastability circuit (UM) and inputs (i-DF, i-DF) of a phase detector (DF), which outputs (o-UM, o-DF) are connected to inputs (r-US′, i-US′) of a control circuit (US′), having output (o-US′) connected to control inputs (s-GPRS, s-GPRS′) of the adjustable speed ring oscillators (GPRS, GPRS′). The outputs (o-UM, o-DF) of the metastability circuit (UM) and the phase detector (DF) are being outputs (o-GL, o-GL) of the random number generator (GL).
