Abstract:
A source driver includes four output switches, two resistors, and a charge-sharing switch. The first output switch and the first resistor are coupled in series to a first output channel of the source driver. The second output switch and the second resistor are coupled in series to a second output channel of the source driver. The third output switch is coupled in parallel to the first output switch. The fourth output switch is coupled in parallel to the second output switch. The charge-sharing switch is coupled between the first resistor and the second resistor. The third output switch and the fourth output switch are controlled to adjust the resistance of the output current path of the source driver.
