Abstract:
1. An electronic device comprising: a first ground node; a second ground node; a logic circuit having a logic ground output, wherein the logic ground output is electrically coupled to the first ground node, and the logic circuit produces a quiescent current (IDDQ) that flows between the first ground node and the second ground node when the electronic device is in an IDDQ evaluation state; a switching element electrically coupled between the first ground node and the second ground node, wherein the switching element is configurable in an electrically non-conductive state when the electronic device is in the IDDQ evaluation state, and the switching element is configurable in an electrically conductive state when the electronic device is not in the IDDQ evaluation state; and an IDDQ evaluation circuit electrically coupled across the first ground node and the second ground node, wherein, when the electronic device is in the IDDQ evaluation state, the IDDQ evaluation circuit is configured to provide a first output signal when an IDDQ indicating voltage across the first and second ground nodes exceeds a reference voltage, wherein the IDDQ indicating voltage is related to the IDDQ that flows between the first ground node and the second ground node.
