Abstract
An electrostatic discharge (ESD) protection circuit protecting a core circuit and including a first high electron mobility transistor (HEMT), a second HEMT, a first current clamping circuit, a second current clamping circuit, and a resistor is provided. The first HEMT is coupled to a first input terminal. The second HEMT is coupled between the first HEMT and a second input terminal. The first current clamping circuit includes a third HEMT. The third HEMT is coupled between the gate of the first HEMT and the second input terminal. The second current clamping circuit is coupled between the first input terminal and the gate of the second HEMT. The resistor is coupled between the first input terminal and the core circuit. The core circuit is coupled to the second input terminal.
