The thesis has done the widespread investigation and study to the domestic and foreign ’ s technologies of analogy low voltage and low power, and analyzes the principles of work, merts and shortcomings of these technologies, based on the absorption of these technologies, it designs a 1. 5v low power rail - to - rail cmos operational amplifier. when designing input stage, in order to enable the input common mode voltage range to achieve rail - to - rail, it does not use the traditional differential input pair, but use the nmos tube and the pmos tube parallel supplementary differential input pair to the structure, and uses the proportional current mirror technology to realize the constant transconductance of input stage. in the middle gain stage design, the current mirror load does not use the traditional standard cascode structure, but uses the low voltage, wide - swing casecode structure which is suitable to work in low voltage. when designing output stage, in order to enhance the efficiency, it uses the push - pull common source stage amplifier as the output stage, the output voltage swing basically reached rail - to - rail. the thesis changes the design of the traditional normal source based on the operational amplifier, uses the differential amplifier with current mirror load to design a normal current source. the normal current source provides the stable bias current and the bias voltage to the operational amplifier, so the stability of operational amplifier is guaranteed. the thesis uses the miller compensate technology with a adjusting zero resistance to compensate the operational amplifier
本論文對國內外的模擬低電壓低功耗技術做了廣泛的調查研究，分析了這些技術的工作原理和優缺點，在吸收這些技術成果基礎上設計了一個1 . 5v低功耗軌至軌cmos運算放大器。在設計輸入級時，為了使輸入共模電壓范圍達到軌至軌，不是採用傳統的差動輸入結構，而是採用了nmos管和pmos管並聯的互補差動輸入對結構，並採用成比例的電流鏡技術實現了輸入級跨導的恆定;在中間增益級設計中，電流鏡負載並不是採用傳統的標準共源共柵結構，而是採用了適合在低壓工作的低壓寬擺幅共源共柵結構;在輸出級設計時，為了提高效率，採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到了軌至軌;本論文改變傳統基準源基於運放的設計，採用了帶電流鏡負載的差分放大器設計了一個基準電流源，給運放提供穩定的偏置電流和偏置電壓，保證了運放的穩定性;並採用了帶調零電阻的密勒補償技術對運放進行頻率補償。 -
In this paper, basic circuit models of cc - current mirror and active impedance are analysed and a new active feedback current mirror is proposed which can achieve larger output impedance, higher current transfer precision, lower power and wider signal dynamic swing
系統地分析了電流傳送器的組成模塊? ?電流鏡和有源電阻，同時提出了一種改進型有源反饋電流鏡電路。該電路能大大提高輸出電阻，同時能保持原電路的電流轉換高精度、低功耗、更寬更良好的輸出電壓動態范圍。 -
She looked in the mirror and pursed up her lips, accompanying it with a little toss of the head, as she had seen the railroad treasurer s daughter do. she caught up her skirts with an easy swing, for had not drouet remarked that in her and several others, and carrie was naturally imitative
她在鏡子面前，學著鐵路會計師女兒的樣子，噘起嘴唇，同時把頭微微一常她輕盈地一擺身子提起裙子-杜洛埃不是在這女孩和別的女人身上一再指出這個動作嗎，而嘉莉是天生善於模仿的。
