摘要: 
本論文中,我們針對顯示器的驅動電路,提出一個低功率消耗及適當的操作速度及有效減小積體電路面積之數位類比轉換器。此數位類比轉換器對於顯示器的效能是一個很重要的部份,因為它負責把數位訊號轉為類比訊號來控制畫素的灰階。
首先,本論文提出一個可十位元數位類比轉換器,我們透過改良傳統電阻式數位類比轉換器,以電晶體分壓方式取代傳統電阻元件,以減小積體電路面積,並達成低功率消耗與適當的操作速度的目的。再經由後級開關電路,把各電晶體分壓電路之輸出的電壓作相加,最後再經過一個具有Sample and Hold 緩衝器將電壓輸出。模擬結顯示,在3.3伏特的電源電壓,頻率為100 KHz下,最大之微分非線性誤差和積分非線性誤差分別約為0.2和0.3最小輸出電壓位階(LSB),靜態消耗功率為16 mW,佈局面積為36 ´ 265 μm2。
其次,提出一個十二位元數位類比轉換器,可用於更高色彩深度要求之平面顯示器,此十二位元數位類比轉換器,利用並行數位資料送入,再轉換成類比的電壓值。數位電路部分是以電晶體分壓方式取代傳統電阻元件,以有效減小積體電路面積,並達成高解析度、低功率消耗為目的,最後再經過一個Sample and Hold 緩衝器將電壓輸出。模擬結顯示,在3.3伏特的電源電壓,頻率為100 KHz下,最大之微分非線性誤差和積分非線性誤差分別約為0.6和0.5最小輸出電壓位階(LSB),靜態消耗功率為26 mW,佈局面積為85 ´ 160.75 μm2。

In this paper, we focused on the driving circuit design for displays. We proposed a digital-to-analog converter (DAC) with low power consumption, and effectively reducing the size of the ICs. This digital-to-analog converter is a very important part for displays, because it takes responsible for transferring digital signals into analog signals to control the grayscale of pixels.
First of all, our 10-bits DAC can applied. We modified the traditional resistive digital-to-analog converters by using the transistors to replace the traditional resistive elements for partial pressure. It can effectively reduce the integrated circuit size and reach a low power consumption. And then after the switch-level circuit, the partial pressure of the transistor output circuit for the sum of the voltage, and finally after a Sample and Hold buffer output voltage. Simulation results show that under the supplying voltage of 3.3 volts, and frequency of 100 KHz. The largest differential nonlinearity error and the integral nonlinearity error are about 0.2 and 0.3, respectively, the least significant bit (LSB) of output voltage, the static power consumption of 1.6 mW , the layout of an area of 1.422*1.322 mm2.
Secondly, a 12 digital analog converter, can be used to request a higher color depth of flat panel displays, the 12-bit digital-to-analog converters was using parallel digital signals import, and then transferring into analog voltage values. Digital part of the transistor circuit pressure to replace traditional resistive element to effectively reduce the circuit area, and reached a high-resolution, low power consumption for the purpose of, and then go through a Sample and Hold buffer output voltage. Simulation results show that under the supplying voltage of 3.3 volts, and frequency of 100 KHz. The largest differential nonlinearity error and the integral nonlinearity error are about 0.6 and 0.5, respectively, the least significant bit (LSB) of output voltage, the static power consumption of 2.6 mW, the layout of an area of 1.374*1.374 mm2.
