Abstract—This paper presents two novel hardware random
number generators (RNGs) based on latch metastability. We
designed the first, the DC-nulling RNG, for extremely low power
operation. The second, the FIR-based RNG, uses a predictive
whitening filter to remove nonrandom components from the
generated bit sequence. In both designs, the use of floating-gate
memory cells allows us to predict and compensate
