Zusammenfassung:This paper presents an oscillator-based TRNG (true random number generator) with jitter amplifier. The proposed jitter amplifier fabricated in a 65nm CMOS process archives 8.4× gain at 25°C, and significantly improves randomness of output bitstream. The TRNG with the jitter amplifier enhances throughput per area by 94% compared to a TRNG with frequency dividers. The prototype TRNG occupies 6,300 μm 2 , generates 2 Mbps random bitstreams, and passes FIPS 140-2 randomness tests and 12 tests in NIST test suite.
