摘要
取代传统运算放大器和临界电压补偿型模拟缓冲器,提出了一种新型的互补式电流镜模拟缓冲器,可以利用在低温多晶硅薄膜晶体管液晶显示器驱动电路上。使用N型电流镜和P型电流镜来交互使用以达到较大的电压输出范围,并且使用一开关控制电路实时控制切换,所以可以提出的电压缓冲器不需要电容或时脉讯号就可以运作,这样可以节省很多布局时所需要的面积,且依然维持良好的线性趋势。
Instead of traditional operational amplifies （OP-AMPs） and threshold voltage compensation type analog buffers, this work presents a novel complementary current mirror （CCM） type analog buffer for integrated data drivers of low-temperature polycrystalline silicon thin-film transistor （LTPS-TFT） displays. The proposed CCM analog buffer makes use of a p-type and an n-type current-mirror-type buffer to achieve large voltage swing. The proposed buffer does not need capacitors and external control signals, so it features compact size and good linearity.
