Abstract
A random number generator is disclosed. In some embodiments, the random number generator comprises two cross-coupled inverter chains, wherein each inverter chain comprises an odd number of gates including an input NAND gate; wherein when a clock signal input into the NAND gate of both inverter chains switches from low to high, the inverter chains start toggling until a noise induced phase difference automatically collapses the toggling after a random number of cycles; and wherein a random number generated by the random number generator is based on the random number of cycles.
