Abstract
A buffer amplifier has high input impedance and is less affected by temperature by supplying independent bias power to each of amplification units. The buffer amplifier includes a bias supply unit supplying bias power having a preset voltage level, an amplification unit receiving preset driving power and the bias power from the bias supply unit to amplify an input signal, and a compensation unit compensating for current unbalance of the driving power supplied to the amplification unit.
