  • Abstract
    Device parameter induced frequency variations in a dense array of nominally identical ring oscillators are measured by sequentially combining the output frequencies into a single frequency modulated signal with the statistical frequency parameters read out by a standard frequency counter. For the example described here, the ring oscillators are designed to capture random variations in MOSFET threshold voltages.
