Abstract: The present invention provides a chip including an I/O pin and an ESD protection circuit. The ESD protection circuit includes a P-type device and a first diode, wherein the P-type device is coupled between the I/O pin and a ground voltage, and an anode of the first diode is directly connected to the I/O pin. In addition, the ESD protection circuit does not comprise any device whose N-type doping/diffusion is directly connected to the I/O pin.
