ABSTRACT:
An amplifier for improving an electrostatic discharge (ESD) characteristic includes an operational amplifier, a first resistor circuit, a first fuse box, a second resistor circuit, and a second fuse box. The operational amplifier includes a first input terminal receiving a first input signal, a second input terminal receiving a second input signal, and an output terminal outputting an output signal. The first resistor circuit is connected between the second input terminal and a first node to prevent ESD from being input to the second input terminal. The first fuse box is connected between the first node and the output terminal of the operational amplifier. The second resistor circuit is connected between the second input terminal and a second node to prevent ESD from being input to the second input terminal. The second fuse box is connected between the second node and a terminal for receiving a ground voltage.
