Patent attributes
Circuits and methods of fabricating circuits that provide electrostatic discharge protection, as well as methods of protecting an integrated circuit from electrostatic discharge. The protection circuit may include a power clamp device, a timing circuit including a resistor and a capacitor that is coupled with the resistor at a node, and a power clamp device coupled with the timing circuit at the node. The capacitor includes a plurality of capacitor elements. The protection circuit further includes a plurality of electronic fuses. Each electronic fuse is coupled with a respective one of the capacitor elements. A field effect transistor may be coupled in parallel with the resistor of the timing circuit, and may be used to bypass the resistor to provide a programming current to any electronic fuse coupled with a capacitor element of abnormally low impedance.
