OUTPUT BUFFER HAVING IMPROVED SLEW RATE OF OUTPUT SIGNAL IN SOURCE DRIVER OF LIQUID CRYSTAL DISPLAY

摘要

An output buffer with an improved slew rate and method thereof. The output buffer may include a differential amplifier, a controller and an output unit. The output buffer may generate a pull signal and a control signal based on received input and output signals. The controller may transition an output node to a control voltage in response to the control signal and a bias voltage. The output unit may maintain the first output signal between a given voltage and the control voltage based on the pull signal and the bias voltage.
