Abstract
A circuit (100) can include a first section (102) that can provide a designated function within an integrated circuit device that can be altered due to current injection at a node (106). A mirror section (104) can mirror the effects of current injection on one or more devices within first section (102) and generate an output indication INJ_EFF representing such effects. In one very particular arrangement, detection of an injected current can be used to prevent false triggering of a switched electrostatic discharge (ESD) current path.
