Abstract
An ESD protection circuit with leakage current reduction function includes a silicon controlled rectifier, a first CMOS inverter, a first transistor, a current mirror, a PMOS capacitor and a resistor. The first CMOS inverter electrically connects with the silicon controlled rectifier. The first transistor comprises a first end, a second end and a third end, wherein the first end electrically connects with the silicon controlled rectifier and the first CMOS inverter, and the current mirror electrically connects with the third end of the first transistor. The PMOS capacitor electrically connects with the current mirror, and the resistor electrically connects with the first CMOS inverter, the second end of the first transistor and the PMOS capacitor.
