Abstract
Provided is a buffer amplifier. The buffer amplifier includes: a replica bias unit dividing an internal power voltage received from an internal power node to generate a bias voltage; an input unit including a first differential amplifier comparing a first differential input signal with the bias voltage to output a first internal signal and a second differential amplifier comparing a second differential input signal with the bias voltage to output a second internal signal; and an output unit including a third differential amplifier comparing the first internal signal with the second internal signal to output a first differential output signal and a second differential output signal.
