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，波動小，主要用于儀表測量等要求整個通頻帶內(nèi)增益恒定的場合。MAX292/296為貝塞爾（Bessel）濾波器，在通頻帶內(nèi)它的群時延時恒定的，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，第一個傳輸零點(diǎn)后輸出將隨頻率的變高而增大，直到第二個零點(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。橢圓型濾波器的一個重要參數(shù)就是過渡比。過渡比定義為阻帶頻率fS與拐角頻率（有時也等同為截止頻率）由時鐘頻率確定。時鐘既可以是外接的時鐘，也可以是自己的內(nèi)部時鐘。使用內(nèi)部時鐘時只需外接一個定時用的電容既可。 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）。 ●既可用外部時鐘也可用內(nèi)部時鐘作為截止頻率的控制時鐘。 ●時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 。雙電源供電時搛-2.375～-5.5V之間的電壓，單電源供電時V--=-V。 V+：正電源。雙電源供電時V+=+2.35～+5.5V,單電源供電時V+=+4.75～+11.0V。 GND：地線。單電源工作時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)中每個元件的影響作用是對于整個頻率響應(yīng)曲線的，某元件值的誤差將會分散到所有的極點(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 時鐘信號 MAX29X系列開頭電容濾波器推薦使用的時鐘信號最高頻率為2.5MHz。根據(jù)對應(yīng)的時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)電容濾波器的時鐘信號既可幅外部時鐘直接驅(qū)動也可由內(nèi)部振蕩器產(chǎn)生。使用外部時鐘時，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時鐘信號發(fā)生器的輸出相連。通過調(diào)整外部時鐘的頻率，可完成濾波器拐角的實(shí)時調(diào)整。 當(dāng)使用內(nèi)部時鐘時，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，V-端接地，而GND端要通過電阻分壓獲得一個電壓參考，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單電源供電時輸入信號范圍取1V～4V,±5V雙電源供電時，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)有一個獨(dú)立的運(yùn)算放大器，這個放大器和濾波器的實(shí)現(xiàn)無直接關(guān)系，用這個放大器可組成一個一階和二階濾波器，用于實(shí)現(xiàn)MAX29X之前的反混疊濾波功能鄞MAX29X之后的時鐘噪聲抑制功能。這個運(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。

研究了散熱器底面尺寸長寬比、鰭的取向及高度對第一諧振頻率、第一諧振頻率處電場增益及輻射方向的影響。并得出結(jié)論:當(dāng)散熱器底面的長寬比≥1時,隨著寬邊尺寸的增加,第一諧振頻率基本保持在2.6 GHz,電場增益基本不變,約為8.3 dB,輻射方向變化較大;鰭的取向?qū)﹄妶鲈鲆婕拜椛浞较蛴绊懖淮?但縱向鰭高度對諧振頻率影響較大。
