ABSTRACT:
In one embodiment, an integrated circuit includes at least one digital leakage detector that includes digital circuitry configured to detect an approximation of a magnitude of the leakage current in transistors of the integrated circuit and configured to generate a digital output representing the approximated magnitude. In another embodiment, a leak detector includes leak circuits and clocked storage devices. Each leak circuit is configured to generate an output signal indicative of a different magnitude of leakage current in a transistor. The clocked storage devices are configured to capture a state representing the output signals of the leak circuits. In another embodiment, a method includes running a test for leakage current in a digital leakage detector, wherein a digital output of the digital leakage detector represents a magnitude of a leakage current being experienced by the integrated circuit during use; and outputting the digital output from the integrated circuit.
