運(yun)算放(fang)(fang)(fang)大(da)(da)器(qi)(qi)（Op-Amp）是模擬電(dian)(dian)路(lu)設計中非常(chang)重要的(de)(de)(de)(de)(de)組成部分，其輸(shu)(shu)(shu)(shu)(shu)(shu)入(ru)和(he)輸(shu)(shu)(shu)(shu)(shu)(shu)出(chu)(chu)動(dong)(dong)態(tai)范圍(wei)(wei)是影響系統(tong)性能的(de)(de)(de)(de)(de)關鍵(jian)因素。要避(bi)(bi)免運(yun)算放(fang)(fang)(fang)大(da)(da)器(qi)(qi)的(de)(de)(de)(de)(de)飽和(he)和(he)截(jie)斷(duan)，需(xu)要對輸(shu)(shu)(shu)(shu)(shu)(shu)入(ru)和(he)輸(shu)(shu)(shu)(shu)(shu)(shu)出(chu)(chu)信(xin)號(hao)(hao)的(de)(de)(de)(de)(de)幅(fu)(fu)度和(he)偏置進行適(shi)當(dang)的(de)(de)(de)(de)(de)控制(zhi)(zhi)(zhi)。首先，飽和(he)主要發生在(zai)(zai)輸(shu)(shu)(shu)(shu)(shu)(shu)入(ru)信(xin)號(hao)(hao)過大(da)(da)，導致運(yun)放(fang)(fang)(fang)內(nei)部的(de)(de)(de)(de)(de)線性放(fang)(fang)(fang)大(da)(da)器(qi)(qi)件達(da)到(dao)其較(jiao)大(da)(da)輸(shu)(shu)(shu)(shu)(shu)(shu)出(chu)(chu)電(dian)(dian)壓時(shi)。這時(shi)，運(yun)放(fang)(fang)(fang)對輸(shu)(shu)(shu)(shu)(shu)(shu)入(ru)信(xin)號(hao)(hao)的(de)(de)(de)(de)(de)響應變得非常(chang)有限(xian)，甚(shen)至完全失去放(fang)(fang)(fang)大(da)(da)能力。為了避(bi)(bi)免這種情況，可以(yi)采取(qu)以(yi)下(xia)措施(shi)：1.選用(yong)具有更高增益-帶寬積(ji)的(de)(de)(de)(de)(de)運(yun)放(fang)(fang)(fang)，以(yi)提(ti)(ti)高運(yun)放(fang)(fang)(fang)的(de)(de)(de)(de)(de)動(dong)(dong)態(tai)范圍(wei)(wei)。2.通過在(zai)(zai)運(yun)放(fang)(fang)(fang)的(de)(de)(de)(de)(de)輸(shu)(shu)(shu)(shu)(shu)(shu)入(ru)端(duan)添加反饋電(dian)(dian)阻，調整放(fang)(fang)(fang)大(da)(da)倍數，以(yi)防止輸(shu)(shu)(shu)(shu)(shu)(shu)入(ru)信(xin)號(hao)(hao)過大(da)(da)。3.限(xian)制(zhi)(zhi)(zhi)輸(shu)(shu)(shu)(shu)(shu)(shu)入(ru)信(xin)號(hao)(hao)的(de)(de)(de)(de)(de)幅(fu)(fu)度，避(bi)(bi)免其在(zai)(zai)運(yun)放(fang)(fang)(fang)的(de)(de)(de)(de)(de)線性范圍(wei)(wei)內(nei)波動(dong)(dong)。其次，截(jie)斷(duan)主要發生在(zai)(zai)運(yun)放(fang)(fang)(fang)的(de)(de)(de)(de)(de)輸(shu)(shu)(shu)(shu)(shu)(shu)出(chu)(chu)接(jie)近其電(dian)(dian)源(yuan)電(dian)(dian)壓時(shi)。這時(shi)，運(yun)放(fang)(fang)(fang)的(de)(de)(de)(de)(de)輸(shu)(shu)(shu)(shu)(shu)(shu)出(chu)(chu)已(yi)經無法再提(ti)(ti)高，導致輸(shu)(shu)(shu)(shu)(shu)(shu)出(chu)(chu)信(xin)號(hao)(hao)的(de)(de)(de)(de)(de)動(dong)(dong)態(tai)范圍(wei)(wei)受到(dao)限(xian)制(zhi)(zhi)(zhi)。為了解(jie)決這個問題，可以(yi)嘗試以(yi)下(xia)方法：1.在(zai)(zai)運(yun)放(fang)(fang)(fang)的(de)(de)(de)(de)(de)輸(shu)(shu)(shu)(shu)(shu)(shu)出(chu)(chu)端(duan)添加一個適(shi)當(dang)的(de)(de)(de)(de)(de)負載(zai)電(dian)(dian)阻，以(yi)限(xian)制(zhi)(zhi)(zhi)輸(shu)(shu)(shu)(shu)(shu)(shu)出(chu)(chu)電(dian)(dian)壓的(de)(de)(de)(de)(de)幅(fu)(fu)度。2.采用(yong)具有更高輸(shu)(shu)(shu)(shu)(shu)(shu)出(chu)(chu)電(dian)(dian)壓擺幅(fu)(fu)的(de)(de)(de)(de)(de)電(dian)(dian)源(yuan)，以(yi)擴展運(yun)放(fang)(fang)(fang)的(de)(de)(de)(de)(de)輸(shu)(shu)(shu)(shu)(shu)(shu)出(chu)(chu)動(dong)(dong)態(tai)范圍(wei)(wei)。上海雷達(da)放(fang)(fang)(fang)大(da)(da)器(qi)(qi)廠商雷達(da)放(fang)(fang)(fang)大(da)(da)器(qi)(qi)的(de)(de)(de)(de)(de)工作頻率范圍(wei)(wei)通常(chang)與(yu)雷達(da)系統(tong)的(de)(de)(de)(de)(de)需(xu)要相(xiang)匹(pi)配。

運(yun)(yun)算放(fang)大器(qi)的(de)(de)(de)(de)震蕩(dang)(dang)(dang)(dang)問題主要源(yuan)(yuan)自電(dian)(dian)(dian)(dian)(dian)路(lu)設(she)計或(huo)操(cao)作不當(dang)(dang)。為了避(bi)免(mian)和解決這(zhe)類(lei)(lei)(lei)問題，以(yi)(yi)下是(shi)一些建(jian)議：1.正確設(she)計電(dian)(dian)(dian)(dian)(dian)路(lu)：在(zai)電(dian)(dian)(dian)(dian)(dian)路(lu)設(she)計中，應(ying)(ying)(ying)(ying)確保運(yun)(yun)放(fang)具(ju)有適(shi)當(dang)(dang)的(de)(de)(de)(de)反饋(kui)回路(lu)，以(yi)(yi)防(fang)(fang)止(zhi)產(chan)生(sheng)振蕩(dang)(dang)(dang)(dang)。此(ci)外，適(shi)當(dang)(dang)選(xuan)(xuan)擇(ze)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)值，確保電(dian)(dian)(dian)(dian)(dian)路(lu)的(de)(de)(de)(de)穩定(ding)性是(shi)非(fei)常重要的(de)(de)(de)(de)。2.選(xuan)(xuan)擇(ze)合(he)適(shi)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)：電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)壓的(de)(de)(de)(de)波(bo)(bo)動或(huo)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)內(nei)阻(zu)(zu)(zu)過大可(ke)(ke)能會導致(zhi)運(yun)(yun)放(fang)輸(shu)出不穩定(ding)。因此(ci)，應(ying)(ying)(ying)(ying)選(xuan)(xuan)擇(ze)穩定(ding)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)，并確保電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)內(nei)阻(zu)(zu)(zu)足夠小(xiao)。3.合(he)理選(xuan)(xuan)擇(ze)運(yun)(yun)放(fang)類(lei)(lei)(lei)：不同類(lei)(lei)(lei)型的(de)(de)(de)(de)運(yun)(yun)放(fang)具(ju)有不同的(de)(de)(de)(de)頻率響(xiang)應(ying)(ying)(ying)(ying)。應(ying)(ying)(ying)(ying)選(xuan)(xuan)擇(ze)具(ju)有合(he)適(shi)頻率響(xiang)應(ying)(ying)(ying)(ying)的(de)(de)(de)(de)運(yun)(yun)放(fang)，以(yi)(yi)避(bi)免(mian)振蕩(dang)(dang)(dang)(dang)。4.增(zeng)加(jia)阻(zu)(zu)(zu)尼電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)：在(zai)反饋(kui)回路(lu)中增(zeng)加(jia)阻(zu)(zu)(zu)尼電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)可(ke)(ke)以(yi)(yi)減少高(gao)頻振蕩(dang)(dang)(dang)(dang)。5.調整(zheng)(zheng)反饋(kui)系(xi)數：通(tong)過調整(zheng)(zheng)反饋(kui)系(xi)數，可(ke)(ke)以(yi)(yi)改變(bian)放(fang)大器(qi)的(de)(de)(de)(de)增(zeng)益(yi)和頻率響(xiang)應(ying)(ying)(ying)(ying)，從而防(fang)(fang)止(zhi)振蕩(dang)(dang)(dang)(dang)。6.合(he)理設(she)計接地：良好的(de)(de)(de)(de)接地設(she)計可(ke)(ke)以(yi)(yi)減少地線電(dian)(dian)(dian)(dian)(dian)位的(de)(de)(de)(de)變(bian)化，從而減少對(dui)運(yun)(yun)放(fang)輸(shu)出的(de)(de)(de)(de)干擾。7.使(shi)用(yong)(yong)補(bu)償電(dian)(dian)(dian)(dian)(dian)容：在(zai)適(shi)當(dang)(dang)的(de)(de)(de)(de)位置(zhi)添加(jia)補(bu)償電(dian)(dian)(dian)(dian)(dian)容可(ke)(ke)以(yi)(yi)調整(zheng)(zheng)電(dian)(dian)(dian)(dian)(dian)路(lu)的(de)(de)(de)(de)頻率響(xiang)應(ying)(ying)(ying)(ying)，以(yi)(yi)防(fang)(fang)止(zhi)振蕩(dang)(dang)(dang)(dang)。8.避(bi)免(mian)過驅動：過驅動會導致(zhi)運(yun)(yun)放(fang)進(jin)入(ru)(ru)非(fei)線性區域，從而產(chan)生(sheng)振蕩(dang)(dang)(dang)(dang)。因此(ci)，應(ying)(ying)(ying)(ying)避(bi)免(mian)對(dui)運(yun)(yun)放(fang)的(de)(de)(de)(de)輸(shu)入(ru)(ru)超過其較大值。9.使(shi)用(yong)(yong)適(shi)當(dang)(dang)的(de)(de)(de)(de)濾波(bo)(bo)器(qi)：在(zai)輸(shu)出端使(shi)用(yong)(yong)適(shi)當(dang)(dang)的(de)(de)(de)(de)濾波(bo)(bo)器(qi)可(ke)(ke)以(yi)(yi)濾掉高(gao)頻噪(zao)聲，從而防(fang)(fang)止(zhi)振蕩(dang)(dang)(dang)(dang)。
