    摘要: Techniques for reducing leakage current during normal operation of an electrostatic discharge (ESD) circuit are described herein. In one embodiment, a circuit comprises an internal circuit and an electrostatic discharge (ESD) rail clamp coupled in parallel to the internal circuit and between first and second power supply rails. The ESD rail clamp is operable to shunt ESD current from the first power supply rail to the second power supply rail via a low resistance shunt path. The ESD rail clamp comprises an ESD trigger circuit configured to detect an ESD event and a plurality of discharging transistors coupled in series. The ESD trigger circuit is configured to turn off the discharging transistors during normal operation and to turn on the discharging transistors to form the low resistance shunt path in response to detection of the ESD event.

    摘要: In a particular embodiment, a circuit includes a power supply, a ground, and a clamping transistor circuit coupled to the power supply and to the ground. The circuit further includes a disable clamp circuit. The disable clamp circuit is coupled to the power supply and is responsive to a second power supply input to selectively disable the clamping transistor circuit by modifying a charging current applied to a capacitor of the clamping transistor circuit. In a particular embodiment, modifying the charging current includes enabling a second charging path. Enabling the second charging path enables charging the capacitor at a higher charging rate than a charging rate associated with charging the capacitor via a first charging path.
