Abstract

In this paper, we proposed high slew-rate and low-power OP-AMP of the data driver for TFT-LCDs. Proposed OP-AMP contains newly developed rail-to-rail class-AB input circuit which enables the low-quiescent current and high slew-rate OP-AMP. The slew-rate and the quiescent current of the proposed OP-AMP are 31.2V/$\mu$sec and 5$\mu$A, respectively.
