Double time-constant for electrostatic discharge clamping |
摘要 |
A method and apparatus is provided for clamping of an electrostatic discharge using multiple time-constants. A rise in a voltage level is detected. A first time-constant is provided to determine whether the rise in the voltage level is caused by an electrostatic event. A clamping function is provided to clamp the voltage level in response to a determination that the rise in the voltage level is caused by the electrostatic event. A second time-constant is provided to provide a time period for maintaining the clamping function for a period of time to substantially extinguish the electrostatic event.
