  1. The paper first reviews the research background and actuality of the filter " s design in china and other country, introduces the meaning of the project and the work of the paper, narrates the theory of the switched - capacitor network and the basic switch building blocks, analyses the related factors of the design of sc filter. such as the selection of the architecture, the trade off of the opamp " s gain, bandwidth, phase margin, slew rate and setting time, the effect of the switch " s on resistor, how to reduce the charge injection and the clock feed - through, the power consumption and the selection of the sampling frequency and so on

    本文首先回顧了濾波器設計的國內外研究背景和現狀,介紹了本課題提出的意義以及本文的主要工作,論述了開關電容網路原理和基本開關模塊,分析了開關電容濾波器設計的相關因素:電路結構的選擇,對運算放大器設計中高增益、寬帶寬、相位裕度、轉換斜率和建立時間等的折中考慮,開關的打開電阻對電路的影響,開關電容電路中怎樣減少電荷注入和時鐘饋通,以及整個電路的功耗問題和采樣頻率的選擇等。
  2. Usually the low power operational amplifier is designed with rail to rail output stage, whose signal dynamirange is small, its output driving force is not strong, here it is designed with voltage displacement stage, and the strong driving force and the low power consumption in this circuit are achieved. with 5v single power, this amplifier consumes only several a, 100khz unity - gain frequency, achieves 80db dc open gain and 55 phase margin for a 100pf load capacitance and a 1m load resistance and other advantages

    通常設計的低功耗軌對軌輸出運算放大器中,由於信號的動態范圍比較小,它的輸出驅動能力不強,這里設計的是採用電平位移電路同時實現了電路的強驅動能力與低功耗,它具有在單電源電壓5v的條件下,靜態工作電流只有幾微安,單位增益帶寬達100k ,開環增益能達80db以上,相位裕度也能達55度,輸出源沉電流達500微安以上等優點。
