Abstract
The present work is focused on the description of a SPAD-based pixel suitable for random bits extraction. Compared to the state-of-the-art, the proposed approach aims at improving the performance of the random generator with respect to possible photon flux variation. Thanks to the adopted methodology, the entropy of the output is maintained almost constant over a wide range of operating conditions. The principle has been validated through simulations and implemented in a compact pixel, suitable for array implementation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
