A new high‐slew‐rate CMOS buffer amplifier consuming a very small quiescent current is proposed for voltage buffer in flat panel displays. This buffer amplifier recursively copies the output driving current and increases the tail current of the input differential pair during slewing. Since the proposed buffer has a possible slew rate higher than 10 V/μs for a load capacitance of 1 nF almost independently of static currents as low as 1 μA, this buffer amplifier is promising for column driver ICs of flat panel displays.
