A new high-slew-rate CMOS buffer amplifier consuming a very small quiescent current is proposed. 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/mu s for a load capacitance of 1 nF almost independently of static currents as low as 1 mu A, this buffer amplifier is promising for column driver ICs of flat panel displays that require low static power consumption, high Current driving capabilities, and small silicon areas.
