Fully Digital Redundant Random Number Generator in CMOS Technology

This communication presents a new fully-digital redundant Random Number Generator. Its structure is that of a standard LFSR, with the difference that it includes one 1-bit ros-RNG in each basic cell. The design is modular, provides reasonable performances - simplicity, low cost and high speed -, it generates "truly" random sequences (i.e. aperiodic and unpredictable) and allows choosing random or pseudorandom sequences. Working like a "truly" random generator, the circuit produces random sequences from the first clock cycle, i.e., user must not wait a latency time to obtain a good sequence.
