Abstract

A technique to produce many high speed uncorrelated truly binary random number generators (RNGs) utilizing least area and power is proposed. The technique relies on the phase noise and jitter of voltage controlled oscillators (VCOs) to generate RNGs using the oscillator sampling technique. To obtain true randomness, the frequency of oscillation of the VCOs is controlled by other RNGs in the array, increasing the jitter spread much more than conventional designs. Parallel high speed uncorrelated random sequences are tested at 1GHz in CMOS 0.18 μm process.
