Electrostatic discharge clamp |
摘要 |
An electrostatic discharge clamp may include a reference generator and a comparator. The electrostatic discharge clamp may be characterized by a time constant. A voltage difference caused by an electrostatic discharge event may activate the electrostatic discharge clamp. The comparator may hold the electrostatic discharge clamp in an active state responsive to a reference voltage provided by the reference generator. A duration of the active state of the electrostatic discharge clamp may facilitate dissipation of the electrostatic discharge event. |

1. A device, comprising:
an initiator path configured to provide an initiator signal; a supply path configured to provide a supply signal; a first gate transistor, coupled to the supply path and a ground path, the first gate transistor configured to clamp the supply path to the ground path responsive to a difference between the initiator signal and the supply signal; a second gate transistor configured to generate a gating signal for the first gate transistor responsive to the difference; a reference generator coupled to the first gate transistor, the reference generator configured to generate a reference signal when the supply path is clamped to the ground path; and a comparator configured to cause the first gate transistor to unclamp the supply path responsive to the reference signal. |
