This dissertation describes an efficient phase compensation and slew rate enhancement techniques in an LCD driver IC. First, I compare five kinds of phase compensation techniques that including the new methods by both theoretical analyses of poles and zeros frequency from transfer function.　In the past, the slew rate enhancement technique by using MOS switches was proposed. However the effect is not enough to satisfy the specification because the effect depends on switching sensitivity of MOS switches that is determined by the threshold voltages of MOSFETs. In order to improve this problem, I propose the MOS switches with level shifter. I propose a new low-power-consumption LCD driver with these methods.HSPICE simulation results demonstrate the effectiveness of the proposed circuit.
