In order to application on high resolution of liquid crystal display, which must reduce differential error voltage in digital-to-analog converter circuit. So, how to reduce the offset voltage of buffer amplifier is important. In the second buffer amplifier circuit, to promote the open-loop gain to reduce offset voltage.

若要使液晶显示器的色彩深度能够大幅提升，就必须采用位元数较高的数位类比转换电路，也就表示其输出的每一灰阶类比电压值的差将会随著位元数的增加而变小，因此输出缓冲放大器的偏移电压就显的特别重要。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
