More Information
Summary:The invention relates to an output buffer and a data driver circuit including the same. The present disclosure relates to an output buffer capable of driving at a high speed and reducing power consumption by increasing a swing rate of an output voltage, and a data driver circuit including the same. The output buffer includes: an input stage that monitors a difference between an input voltage and an output voltage; a current summing stage that generates an amplified current and a control voltage according to a difference between the input voltage and the output voltage monitored by the input stage; an output stage that performs a pull-up operation or a pull-down operation according to the control voltage output from the current summing stage to generate an output voltage at an output terminal; and a swing boost circuit performing a swing boost operation of adjusting some of the currents supplied from the current summing stage to the input stage according to a difference between the input voltage and the output
