本論文主要目的是要設計薄膜電晶體液晶顯示器的垂直驅動電路。此電路可達6位元的解析度,218種顏色,並有12組輸出。其中在數位─類比轉換器的架構上,採用了兩種不同的設計方式,一種是利用電阻─串方式,另一種是利用開關─電容方式。
整個電路的電晶體是利用聯電0.5微米製程的模型完成,並以HSPICE模擬輸入時鐘60MHz時的結果。
The purpose of this thesis is to design the TFT-LCD column driver. This driver contains 6-bit resolution for one sub-pixel, 218 colors and the outputs for 12 sub-pixels. In the scheme of the DAC design, we use two different structures. One is the R-string DAC, and the other is the SC-DAC.
The transistors in the whole circuit use the UMC 0.5um processing model to realize. And we use the HSPICE tool to simulate the driver with the input clock frequency being 60 MHz.
