Abstract
An output driving system includes an output driver, a first ESD (Electrostatic Discharge) protection circuit, a second ESD protection circuit, a first differential amplifier, a second differential amplifier, a first capacitor, and a second capacitor. The output driver has a first output node for outputting a first output voltage, and a second output node for outputting a second output voltage. The first differential amplifier generates a first amplified voltage according to the first output voltage and the second output voltage. The first capacitor has a first terminal for receiving the first amplified voltage, and a second terminal coupled to the first output node. The second differential amplifier generates a second amplified voltage according to the first output voltage and the second output voltage. The second capacitor has a first terminal for receiving the second amplified voltage, and a second terminal coupled to the second output node.
