內(nèi)容簡介

　　本書詳細(xì)地闡述了一種流水線12bit，75MSamples／s的ADC試驗(yàn)?zāi)Ｐ?。該轉(zhuǎn)換器在第1級4位粗轉(zhuǎn)換之后的余量放大中，以簡單的開環(huán)增益級代替精確的閉環(huán)運(yùn)放，比傳統(tǒng)實(shí)現(xiàn)方法（相同類型的商用產(chǎn)品）節(jié)省功耗60％以上，同時也提高了速度。對于這種替代所產(chǎn)生的增益的線性與非線性誤差，本書在分析與建立誤差模型的基礎(chǔ)上，提出了基于統(tǒng)計學(xué)的可行的后臺數(shù)字校準(zhǔn)技術(shù)。實(shí)踐證明，通過復(fù)雜的數(shù)字電路的算法可估算這些誤差并實(shí)時地對輸出進(jìn)行校準(zhǔn)。 .我國在集成ADC方面，無論是設(shè)計還是其實(shí)現(xiàn)離國際先進(jìn)水平的差躡都較大，而關(guān)于ADC設(shè)計方面的圖書也鮮見出版。因此，本書的引進(jìn)出版，對我國集成電路設(shè)計，特別是高速、高精度和低功耗ADC設(shè)計方面將具有重要意義。...
