本論文設計實現一個 6 位元 1GS/s 的數位類比轉換器,此數位類比轉換器使用的是全溫度計編碼電流操縱式的架構。為了降低因為製程變異使得電流源裡的電晶體之間造成不匹配的情況,我們討論了有關電流電晶體尺寸設計,並且討論如何使 DNL 與 INL 達到小於 0.1 個 LSB 。而由梯度所引起的不匹配錯誤,透過一個四象限中心點對稱的佈局方式來消除。
使用的是 TSMC 0.35 um 的標準 CMOS 製程,供應電壓為 3.3 V , DNL ±0.1 LSB , INL ±0.3 LSB ,當輸入的時脈訊號在 10M 時,給定輸入弦波頻率 1MHz ,可得到 SFDR= 21.31dB ,功率消耗為 35.2 mW。

This thesis designs a 6-bit 1GS/s Digital-to-Analog Converter (DAC). The DAC uses full thermometer-coded current steering architecture. In order to degrade the mismatch between the transistors in the current source, we discuss about the size design of the current transistor. And we discuss how to make the DNL and INL to reach below 0.1 LSB. Gradient-induced mismatch errors are compensated by using a quadrant centro-symmetric layout.
It uses TSMC 0.35 um standard CMOS technology, the supply voltage is 3.3 V. DNL is about 0.1 LSB, INL is about 0.3 LSB. When clock in = 10M, the spurious-free dynamic rang (SFDR) of 21.31 dB can be achieved with 1M digital sine input, and the total power dissipation is 35.2 mW.
