Current - mode continuous - time filters based on mocc 的電流模式連續(xù)時間濾波器
Fully integrated continuous - time filters based on otra ' s 的電壓模式全集成連續(xù)時間濾波器
Current - mode continuous - time filter is current - mode circuit , so it has characteristics of current - mode circuit 本文還對版圖基本理論以及濾波器電路的版圖的實(shí)現(xiàn)進(jìn)行了研究。
Typical current - mode continuous - time filters include current - mode filter based on current conveyor , current - mode filter based on ota - c and current - mode filter based on current mirrors . they are rapidly developed in bandwidth , speed , precision , etc , and they bring the filter theories to noble times of fully integrated system development . there are many articles on continuous - time filter based on ota in nearly two years 在對版圖設(shè)計(jì)的步驟、方法、所用軟件以及cmos基礎(chǔ)和工藝流程這些版圖設(shè)計(jì)所需的基本理論研究的基礎(chǔ)上,給出了本設(shè)計(jì)中用到的電容和nmos及pmos管版圖結(jié)構(gòu),得到了具體ota - c濾波器版圖,并對版圖進(jìn)行了幾何設(shè)計(jì)規(guī)則檢查和版圖驗(yàn)證。
Continuous - time filter needn ’ t a / d switch , data processing , d / a switch technique and so on to finish filtering function with analog signal like digital filter . and it needn ’ t switch action to sample data in the discrete time with analog signal like switched capacitor filter . so continuous - time filter has several advantages , such as high processing speed , simple circuit configuration , and low power consumption 對每種方法都進(jìn)行了詳細(xì)的推導(dǎo),總結(jié)了每種設(shè)計(jì)方法的設(shè)計(jì)步驟、適用場合,舉例用每種設(shè)計(jì)方法對具體濾波器進(jìn)行了電路設(shè)計(jì)、靈敏度特性分析、失真特性分析等,并用計(jì)算機(jī)仿真驗(yàn)證了電路方案。
