高速ADC、DAC測試原理及測試方法

隨著數(shù)字信號處理技術(shù)和數(shù)字電路工作速度的提高，以及對于系統(tǒng)靈敏度等要求的不斷提高，對于高速、高精度的ADC、DAC的指標(biāo)都提出了很高的要求。比如在移動(dòng)通信、圖像采集等應(yīng)用領(lǐng)域中，一方面要求ADC有比較高的采樣率以采集高帶寬的輸入信號，另一方面又要有比較高的位數(shù)以分辨細(xì)微的變化。因此，保證ADC/DAC在高速采樣情況下的精度是一個(gè)很關(guān)鍵的問題。ADC/DAC芯片的性能測試是由芯片生產(chǎn)廠家完成的，需要借助昂貴的半導(dǎo)體測試儀器，但是對于板級和系統(tǒng)級的設(shè)計(jì)人員來說，更重要的是如何驗(yàn)證芯片在板級或系統(tǒng)級應(yīng)用上的真正性能指標(biāo)。ADC的主要參數(shù)ADC的主要指標(biāo)分為靜態(tài)指標(biāo)和動(dòng)態(tài)指標(biāo)2大類。靜態(tài)指標(biāo)主要有：Differ ential Non-Li nearity（DNL）ntegral Non-Li nearity（INL）Of fset Error ull Scale Gain Error動(dòng)態(tài)指標(biāo)主要有：
