由兩個(gè)較低分辨率的閃爍式ADC構(gòu)成較高分辨率的半閃爍式ADC或分級(jí)型ADC是當(dāng)今世界制造高速ADC的主要方式。圖2所示是一個(gè)8位的兩級(jí)并行半閃爍式ADC的原理框圖。其轉(zhuǎn)換過(guò)程分為兩步：
*步是粗化量化。先用并行方式進(jìn)行高4位的轉(zhuǎn)換，作為轉(zhuǎn)換后的高4位輸出，同時(shí)再把數(shù)字輸出進(jìn)行D/A轉(zhuǎn)換，恢復(fù)成模擬電壓。
第二步是進(jìn)一步細(xì)化量化。把原輸入電壓與D/A 轉(zhuǎn)換器輸出的模擬電壓相減，其差值再進(jìn)行低4全的A/D轉(zhuǎn)換。然后將上述兩級(jí)A/D轉(zhuǎn)換器的數(shù)字輸出并聯(lián)后作為總的輸出。這樣，在轉(zhuǎn)換速度上作出了一點(diǎn)犧牲，但解決了分辨率提高和元件數(shù)目刷增的矛盾。
