Abstract:
This paper proposes a low-power, small formfactor all-digital RNG utilizing a concept of capacitive coupling between two ROs to amplify jitter and a dual-edge sampling scheme to increase the data rate. It is the most useful in battery-powered IoT applications where both energy and silicon area are critical constraints. The capacitive coupling effect with all digital circuit allows our design to operate reliably over a wide range of supply voltages. It consumes only 1.85 pJ/bit at 1V supply and 67 Mb/s, which scales down to 25 fJ/bit at 0.3 V, 5 Mb/s. Its overall FOM is 1.7×104, which is more than 3× better than existing designs.
