8階開關(guān)電容濾波器MAX29X系列的應(yīng)用設(shè)計(jì)

MAX29X是美國MAXIM公司生瓣的8階開關(guān)電容低通濾波器,由于價(jià)格便宜、使用方便、設(shè)計(jì)簡單，在通訊、信號自理等領(lǐng)域得到了廣泛的應(yīng)用。本文就其工作原理、電氣參數(shù)、設(shè)計(jì)注意事項(xiàng)等問題作了討論，具有一定的實(shí)用參考價(jià)值。關(guān)鍵詞：開關(guān)電容、濾波器、設(shè)計(jì) 1 引言開關(guān)電容濾波器在近些年得到了迅速的發(fā)展，世界上一些知名的半導(dǎo)體廠家相繼推出了自己的開頭電容濾波器集成電路，使形狀電容濾波器的發(fā)展上了一個(gè)新臺階。 MAXIM公司在模擬器件生產(chǎn)領(lǐng)域頗具影響，它生產(chǎn)MAX291/292/293/294/295/296/297系列8階低通開關(guān)電容濾波器由于使用方便（基本上不需外接元件）、設(shè)計(jì)簡單（頻率響應(yīng)函數(shù)是固定的，只需確定其拐角頻率即截止頻率)、尺寸小（有8-pin DIP封裝）等優(yōu)點(diǎn)，在ADC的反混疊濾波、噪聲分析、電源噪聲抑制等領(lǐng)域得到了廣泛的應(yīng)用。 MAX219/295為巴特活思（型濾波器，在通頻帶內(nèi)，它的增益最穩(wěn)定，波動(dòng)小，主要用于儀表測量等要求整個(gè)通頻帶內(nèi)增益恒定的場合。MAX292/296為貝塞爾（Bessel）濾波器，在通頻帶內(nèi)它的群時(shí)延時(shí)恒定的，相位對頻率呈線性關(guān)系，因此脈沖信號通過MAX292/296之后尖峰幅度小，穩(wěn)定速度快。由于脈沖信號通過貝塞爾濾波器之后所有頻率分量的延遲時(shí)間是相同的，故可保證波形基本不變。關(guān)于巴特活和貝塞爾濾波器的特性可能圖1來說明。圖1的蹤跡A為加到濾波器輸入端的3kHz的脈沖，這里我們把濾波器的截止頻率設(shè)為10kHZ。蹤跡B通過MAX292/296后的波形。從圖中可以看出，由于MAX292/296在通帶內(nèi)具有線性相位特性，輸出波形基本上保持了方波形狀，只是邊沿處變圓了一些。方波通過MAX291/295之后，由于不同頻率的信號產(chǎn)生的時(shí)延不同，輸出波形中就出現(xiàn)了尖峰(overshoot)和鈴流(ringing)。 MAX293/294/297為8階圓型（Elliptic）濾波器，它的滾降速度快，從通頻帶到阻帶的過渡帶可以作得很窄。在橢圓型濾波器中，第一個(gè)傳輸零點(diǎn)后輸出將隨頻率的變高而增大，直到第二個(gè)零點(diǎn)處。這樣幾番重復(fù)就使阻事賓頻響呈現(xiàn)波浪形，如圖2所示。阻帶從fS起算起，高于頻率fS處的增益不會(huì)超過fS處的增益。在橢圓型濾波中，通頻帶內(nèi)的增益存在一定范圍的波動(dòng)。橢圓型濾波器的一個(gè)重要參數(shù)就是過渡比。過渡比定義為阻帶頻率fS與拐角頻率（有時(shí)也等同為截止頻率）由時(shí)鐘頻率確定。時(shí)鐘既可以是外接的時(shí)鐘，也可以是自己的內(nèi)部時(shí)鐘。使用內(nèi)部時(shí)鐘時(shí)只需外接一個(gè)定時(shí)用的電容既可。在MAX29X系列濾波器集成電路中，除了濾波器電路外還有一個(gè)獨(dú)立的運(yùn)算放大器（其反相輸入端已在內(nèi)部接地）。用這個(gè)運(yùn)算放大器可以組成配合MAX29X系列濾波器使用后的濾波、反混濾波等連續(xù)時(shí)間低通濾波器。下面歸納一下它們的特點(diǎn)： ●全部為8階低通濾波器。MAX291/MAX295為巴特沃思濾波器；MAX292/296為貝塞爾濾波器；MAX293/294/297為橢圓濾波器。 ●通過調(diào)整時(shí)鐘，截止頻率的調(diào)整范圍為：0.1Hz～25kHz（MAX291/292/293*294）；0.1Hz～kHz（MAX295/296/297）。 ●既可用外部時(shí)鐘也可用內(nèi)部時(shí)鐘作為截止頻率的控制時(shí)鐘。 ●時(shí)鐘頻率和截止頻率的比率：10∶1(MAX291/292/293/294);50∶1(MAX295/296/297)。 ●既可用單+5V電源供電也可用±5V雙電源供電。 ●有一個(gè)獨(dú)立的運(yùn)算放大器可用于其它應(yīng)用目的。 ●8-pin DIP、8-pin SO和寬SO-16多種封裝。2 管腳排列和主要電氣參數(shù) MAX29X系列開頭電容濾波器的管腳排列如圖3所示。管腳功能定義如下： CLK：時(shí)鐘輸入。 OP OUT：獨(dú)立運(yùn)放的輸出端。 OP INT：獨(dú)立運(yùn)放的同相輸入端。 OUT：濾波器輸出。 IN：濾波器輸入。 V-：負(fù)電源。雙電源供電時(shí)搛-2.375～-5.5V之間的電壓，單電源供電時(shí)V--=-V。 V+：正電源。雙電源供電時(shí)V+=+2.35～+5.5V,單電源供電時(shí)V+=+4.75～+11.0V。 GND：地線。單電源工作時(shí)GND端必須用電源電壓的一半作偏置電壓。 NC：空腳，無連線。 MAX29X的極限電氣參數(shù)如下：電源（V+～V-）：12V 輸入電壓（任意腳）：V--0.3V≤VIN≤V++0.3V 連續(xù)工作時(shí)的功耗：8腳塑封DIP：727mW；8腳SO：471mW；16腳寬SO：762mW；8腳瓷封DIP：640mW。工作溫度范圍：MAX29-C-：0℃～+70℃；MAX29-E-：-40℃～+85℃；MAX29-MJA：-55℃～+125℃；保存溫度范圍：-65℃～+160℃；焊接溫度（10秒）：+300℃；大多數(shù)的形狀電容濾波器都采用四節(jié)級連結(jié)構(gòu)，每一節(jié)包含兩個(gè)濾波器極點(diǎn)。這種方法的特點(diǎn)就是易于設(shè)計(jì)。但采用這種方法設(shè)計(jì)出來的濾波器的特性對所用元件的元件值偏差很敏感。基于以上考慮，MAX29X系列用帶有相加和比例功能的開關(guān)電容持了梯形無源濾波器，這種方法保持了梯形無源濾波器的優(yōu)點(diǎn)，在這種結(jié)構(gòu)中每個(gè)元件的影響作用是對于整個(gè)頻率響應(yīng)曲線的，某元件值的誤差將會(huì)分散到所有的極點(diǎn)，因此不值像四節(jié)級連結(jié)構(gòu)那樣對某一個(gè)極點(diǎn)特別明顯的影響。3 MAX29X的頻率特性 MAX29X的頻率特性如圖4所示。圖中的fs都假定為1kHz。4 設(shè)計(jì)考慮下面對MAX29X系列形狀電容濾波器的使用做些討論。4.1 時(shí)鐘信號 MAX29X系列開頭電容濾波器推薦使用的時(shí)鐘信號最高頻率為2.5MHz。根據(jù)對應(yīng)的時(shí)鐘頻率和拐角頻率的比值，MAX291/MAX292/MAX293/MAX294的拐角頻率最高為25kHz.MAX295/MAX296/MAX297的拐角頻率最高為50kHz 。 MAX29X系列開關(guān)電容濾波器的時(shí)鐘信號既可幅外部時(shí)鐘直接驅(qū)動(dòng)也可由內(nèi)部振蕩器產(chǎn)生。使用外部時(shí)鐘時(shí)，無論是采用單電源供電還是雙電源供電，CLK可直接和采用+5V供電的CMOS時(shí)鐘信號發(fā)生器的輸出相連。通過調(diào)整外部時(shí)鐘的頻率，可完成濾波器拐角的實(shí)時(shí)調(diào)整。當(dāng)使用內(nèi)部時(shí)鐘時(shí)，振蕩器的頻率由接在CLK端上的電容VCOSC決定： fCOSC (kHz)=105/3COSC (pF) 4.2 供電 MAX29X系列開關(guān)電容濾波器既可用單電源工作也可用雙電源工作。雙電源供電時(shí)的電源電壓范圍為±2.375～±5.5V。在實(shí)際電路中一般要在正負(fù)電源和GND之間接一旁路電容。當(dāng)采用單電源供電時(shí)，V-端接地，而GND端要通過電阻分壓獲得一個(gè)電壓參考，該電壓參考的電壓值為1/2的電源電壓，參見圖5。4.3 輸入信號幅度范圍限制 MAX29X允許的輸入信號的最大范圍為V--0.3V～V++0.3V。一般情況下在+5V單電源供電時(shí)輸入信號范圍取1V～4V,±5V雙電源供電時(shí)，輸入信號幅度范圍取±4V。如果輸入信號超過此范圍，總諧波失真THD和噪聲就大大增加；同樣如果輸入信號幅度過小（VP-P＜1V），也會(huì)造成THD和噪聲的增加。4.4 獨(dú)立運(yùn)算放大器的用法 MAX29X中都設(shè)計(jì)有一個(gè)獨(dú)立的運(yùn)算放大器，這個(gè)放大器和濾波器的實(shí)現(xiàn)無直接關(guān)系，用這個(gè)放大器可組成一個(gè)一階和二階濾波器，用于實(shí)現(xiàn)MAX29X之前的反混疊濾波功能鄞MAX29X之后的時(shí)鐘噪聲抑制功能。這個(gè)運(yùn)算放大器的反相端已在內(nèi)部和GND相連。圖6是用該獨(dú)立運(yùn)放組成的2階低通濾波器的電路，它的拐角頻率為10kHz,輸入阻抗為22Ω,可滿足MAX29X形狀電容濾波器的最小負(fù)載要求（MAX29X的輸出負(fù)載要求不小于20kΩ）可以通過改變R1、R2、R3、C1、C2的元件值改變拐角頻率。具體的元件值和拐角頻率的對應(yīng)關(guān)系參見表1。

單片機(jī)名詞解釋

總線:指能為多個(gè)部件服務(wù)的信息傳送線，在微機(jī)系統(tǒng)中各個(gè)部件通過總線相互通信。地址總線:它是傳送由CPU發(fā)出的用于選擇要訪問的器件或部件的地址。數(shù)據(jù)總線:它是用來傳送微型機(jī)系統(tǒng)內(nèi)的各種類型的數(shù)據(jù)。匯編：是能完成一定任務(wù)的機(jī)器指令的集合。二進(jìn)制數(shù):只有0和1兩個(gè)數(shù)碼，基數(shù)為二。16進(jìn)制數(shù):采用0、1、2、3、4、5、6、7、8、9、A、B、C、D、E、F等16個(gè)數(shù)碼，其中A-F相應(yīng)的十進(jìn)數(shù)為10-15，基數(shù)是16。指令:是計(jì)算機(jī)所能執(zhí)行的一種基本操作的描述，是計(jì)算機(jī)軟件的基本單元。存儲器:用來存放計(jì)算機(jī)中的所有信息：包括程序、原始數(shù)據(jù)、運(yùn)算的中間結(jié)果及最終結(jié)果等。

單片機(jī)原理及應(yīng)用實(shí)驗(yàn)指導(dǎo)（山東農(nóng)業(yè)大學(xué)）

1.1MCS51實(shí)驗(yàn)系統(tǒng)安裝與啟動(dòng)1.DVCC系列實(shí)驗(yàn)系統(tǒng)在出廠時(shí)均為51狀態(tài)對DVCC—52196JH機(jī)型：SK1位1—5置ON位置，位6—10置OFF對DVCC—5286JH和DVCC—598JH機(jī)型：a.SK1位1—5置ON，位6—10置OFF；b.SK2位1—2置ON；c.SK3置ON；d.SK4置OFFe.臥式KBB置51、96位置,立式KBB1開關(guān)置51、88位置（只對DVCC—598JH/JH+）；f.DL1—DL4連1、22.如果系統(tǒng)用于仿真外接用戶系統(tǒng)，將40芯仿真電纜一頭插入系統(tǒng)中J6插座，另一頭插入用戶系統(tǒng)的8051CPU位置，注意插入方向，仿真頭上小紅點(diǎn)表示第一腳，對應(yīng)用戶8051CPU第一腳。3.接上+5V電源，將隨機(jī)配備的2芯電源線，紅線接入外置電源的+5V插孔，黑線接入外置電源地插座。上電后，DVCC系列實(shí)驗(yàn)系統(tǒng)上顯示“P.”閃動(dòng)。如果是獨(dú)立運(yùn)行，按DVCC系列用戶手冊進(jìn)入鍵盤管理監(jiān)控，就能馬上做實(shí)驗(yàn)。鍵盤管理監(jiān)控操作詳見第一分冊第四章。如果連上位機(jī)工作，必須將隨機(jī)配備的D型9芯插頭一端插入DVCC系統(tǒng)J2插座，另一端插入上位機(jī)串行口COM1—COM2任選。然后按DVCC實(shí)驗(yàn)系統(tǒng)PCDBG鍵，再運(yùn)行上位機(jī)上的DVCC聯(lián)機(jī)軟件，雙方建立通信，往后詳細(xì)操作見用戶手冊第五章。如果電源內(nèi)置，只需打開～220V電源開關(guān)即可。
