   本論文對國內(nèi)外的模擬低電壓低功耗技術(shù)做了廣泛的調(diào)查研究,分析了這些技術(shù)的工作原理和優(yōu)缺點,在吸收這些技術(shù)成果基礎(chǔ)上設(shè)計了一個1 . 5v低功耗軌至軌cmos運算放大器。在設(shè)計輸入級時,為了使輸入共模電壓范圍達(dá)到軌至軌,不是采用傳統(tǒng)的差動輸入結(jié)構(gòu),而是采用了nmos管和pmos管并聯(lián)的互補(bǔ)差動輸入對結(jié)構(gòu),并采用成比例的電流鏡技術(shù)實現(xiàn)了輸入級跨導(dǎo)的恒定;在中間增益級設(shè)計中,電流鏡負(fù)載并不是采用傳統(tǒng)的標(biāo)準(zhǔn)共源共柵結(jié)構(gòu),而是采用了適合在低壓工作的低壓寬擺幅共源共柵結(jié)構(gòu);在輸出級設(shè)計時,為了提高效率,采用了推挽共源級放大器作為輸出級,輸出電壓擺幅基本上達(dá)到了軌至軌;本論文改變傳統(tǒng)基準(zhǔn)源基于運放的設(shè)計,采用了帶電流鏡負(fù)載的差分放大器設(shè)計了一個基準(zhǔn)電流源,給運放提供穩(wěn)定的偏置電流和偏置電壓,保證了運放的穩(wěn)定性;并采用了帶調(diào)零電阻的密勒補(bǔ)償技術(shù)對運放進(jìn)行頻率補(bǔ)償。
