True Random Number Generator - Analog Noise Source

Purpose

The True Random Number Generator (TRNG) Analog Noise Source is a physical entropy source compliant with the AIS 31 standard.

Features

▪ robust, fully-integrated, state-of-the-art physical entropy source;
▪ differential jitter extraction through a PLL-based fully symmetric architecture;
▪ stochastic model of the entropy source for AIS 31 certification;
▪ asynchronous random clock signal output;
▪ random stream synchronization through an external sampling clock;
▪ typical characteristics of a 55 nm implementation:
− compliant with the AIS 31 standard (Method A, Procedure A) up to 100 kbit/s;
− with optional digital post-processing: fully compliant with the AIS 31 (Method A & B) and NIST SP 800-90B standards up to 100 kbit/s;
− startup time shorter than 80 µs;
− power-supply voltage range: 1.2 V ±10%;
− operating current smaller than 40 µA;
− standby current lower than 1 µA;
− operating junction temperature range: -40°C to 125°C;
− silicon area smaller than 0.02 mm².
▪ silicon proven in 130 nm, 110 nm, 65 nm and 55 nm CMOS processes;
▪ digital post-processing available separately.

Deliverables

▪ GDSII stream and layer map file;
▪ Library Exchange Format (LEF) file;
▪ Circuit Description Language (CDL) netlist;
▪ VHDL behavioral model and Liberty Timing File (.lib);
▪ design specification.
