摘要

This study proposes a low-quiescent current two-input/output buffer amplifier for LCD applications. A current reuse technique is employed in the output stage of the buffer amplifier to reduce the quiescent current consumption. An experimental prototype 6-bit LCD column driver with the proposed buffer amplifiers implemented in a 0.35-μm CMOS technology demonstrates that an average value of 0.6 μA static current is consumed in one channel driver. The settling time to settle within 0.2% of the final voltage is 6 μs under a 30-K-resistance and 30-pF-capacitance load. The area of this two-input/output buffer amplifier is 21.5 μm × 190 μm.
