Abstract
The present invention provides an electrostatic discharge protection device, which is used to protect an integrated circuit. The protection device is coupled with a high voltage source and a low voltage source. The protection device includes: a discharge transistor having a drain coupled with the high voltage source, and a source coupled with the low voltage source; an inverter having an output coupled with the gate of the discharge transistor; a resistor, coupled to the input of the high voltage source and the inverter; a first capacitor, coupled to the input of the inverter and the low voltage source; and, a second capacitor, which is connected with the resistor in parallel.
