Abstract
Disclosed herein are embodiments of electrostatic discharge (ESD) protection circuits. In certain embodiments an ESD protection circuit may include two series resistor-capacitor (RC) circuits. One series RC circuit may have a short time constant and may selectively activate a current shunt between two power rails in response to an ESD event. Accordingly, the ESD circuit may be able to respond to fast ramping ESD events. The other series RC circuit has a longer time constant, and maintains the current shunt in an active state for a sufficient amount of time to allow the ESD event to be completely discharged.
