This is achieved processing time series of pulses endogenously generated in a dedicated Silicon structure. Single pulse seeds, originated by trapping and de-trapping of charge carriers from states in the band gap of Silicon, boosted by a high electric field in the structure gain energy and by impact ionization trigger avalanches corresponding to millions of electrons in a nanosecond, namely one billionth of a second. This self-amplified current pulse can be tagged and time stamped, resulting in a random time series of independent pulses, actually following the Poisson distribution.

Analyzing it with a simple but robust algorithm, randomness can be extracted and turned into bits.

The principle and its embodiment are protected by a patent application, International Publication Number WO 2020/070641 A1, already granted in Italy and being extended in Europe, U.S., China, Japan and Korea, following a very favorable referee’s report during the international PCT phase.

The principle has been integrated into a single generator board, with a bit stream of about 100 kbps, building block of a product and service platform ranging from hardware and software for a Randomness Farm to miniaturization into a proprietary chip.
