    摘要: A slew rate boost circuit for an output buffer and an output buffer circuit for a source driver having the same are provided. In an output buffer including a pull-up unit providing a buffer output signal in a first level by receiving a buffer input signal and performing pull-up operation and a pull-down unit providing a buffer output signal in a second level having opposite phase from the first level by receiving the buffer input signal and performing pull-down operation, the slew rate boost circuit includes a first comparator generating a first boost signal to boost pull-up operation of the pull-up unit of the output buffer by inputting a first input signal and a second input signal and a second comparator generating a second boost signal to boost pull-down operation of the pull-down unit of the output buffer by inputting the first input signal and the second input signal.

    摘要: A driving circuit for Liquid Crystal Display (LCD) device includes a unity-gain operation amplifier (OP amp), three switches, and two capacitors. The unity-gain OP amp buffers and carries a signal voltage on a transmission line. The first switch switches a connection between a noninverting terminal of the unity-gain OP amp and an input line of the signal voltage. One end of the second switch is connected to the input line of the signal voltage. One end of the third switch is connected to the noninverting terminal of the unity-gain OP amp. The first capacitor is connected between the other end of the third switch and the other end of the second switch. The second capacitor is connected between the other end of the first capacitor and the ground voltage terminal.
