Abstract
A timing margin sensor includes a delay circuit to generate a calibrated delay that corresponds to a known delay value of a logic circuit. Circuitry locks a first delay produced by the delay circuit to a clock period of a clock signal that is associated with the known delay value. A programmable selector adjusts the first delay to generate the calibrated delay, the calibrated delay including a timing margin component. Circuitry detects a change in supply voltage provided to the logic circuit based on a detected change in the calibrated delay. Clock adjustment circuitry selectively changes the clock period based on the detected change in the calibrated delay.
