  • ELECTROSTATIC DISCHARGE CIRCUIT FOR MULTI-VOLTAGE RAIL THIN-GATE OUTPUT DRIVER
    Publication number: 20230275424
    Abstract: An ESD protection circuit in an interface circuit has a first diode coupled between a first power source of an integrated circuit device and an input/output pad of the integrated circuit device, a second diode coupled between a second power source of the integrated circuit device and the input/output pad, and a resistive element that couples the second diode to the first diode and to the input/output pad. The first power source supplies a driver circuit coupled to the input/output pad. The second power source supplies one or more core circuits of the integrated circuit device. The resistive element may be implemented as an interconnect configured to provide a resistance that produces a voltage differential between a terminal of the second diode and a corresponding terminal of the first diode during an electrostatic discharge event.
