cod-weyneeye hawleed?
Waa maxay cod-weyneeye shaqaynaya?
Amplifiers Operational (op-amps) waa unugyo wareeg ah oo leh qodob cod-weyneyn sare leh.Wareegyada wax ku oolka ah, waxaa badanaa lagu daraa shabakad jawaab celin ah si ay u sameeyaan cutub shaqeynaya.Waa cod-weyneeye leh wareeg isku xidhid gaar ah iyo jawaab celin.Calaamadda wax-soo-saarka waxay noqon kartaa natiijada hawlaha xisaabeed sida isku-darka, kala-goynta, kala-soocidda, ama is-dhexgalka calaamadda gelinta.Magaca "amplifier-ga hawlgalka" waxa uu ka yimid isticmaalkiisii hore ee kombuyuutarrada analoogga ah si loo fuliyo hawlaha xisaabta.
Magaca "amplifier-ga hawlgalka" waxa uu ka yimid isticmaalkiisii hore ee kombuyuutarrada analoogga ah si ay u qabtaan hawlo xisaabeed.Cod-weyneeye-hawleedku waa unug wareeg ah oo loogu magac daray dhinaca shaqada waxaana lagu hirgelin karaa aaladaha kala duwan ama chips-ka semiconductor-ka.Iyadoo horumarinta tignoolajiyada semiconductor, badiyaa op-amps waxay u jiraan hal jajab.Waxaa jira noocyo badan oo kala duwan oo op-amps ah, kuwaas oo si weyn loogu isticmaalo warshadaha elektiroonigga ah.
Marxaladda wax gelinta waa wareegga cod-weyneeye ka duwan oo leh iska caabin wax-gelineed oo sarreeya iyo eber awoodda xakamaynta;Marxaladda dhexe waxay u badan tahay kororka korantada, oo leh korantada korantada oo sarreeya, oo guud ahaan ka kooban wareegga cod-weyneeye ee caadiga ah;cirifka wax soo saarka wuxuu ku xiran yahay culeyska, oo leh awood qaadis xoog leh iyo sifooyin iska caabin ah oo hooseeya.Cod-weyneyaasha hawlgalka waxaa loo adeegsadaa codsiyo kala duwan.
Kala soocidda
Marka loo eego cabbirada cod-weyneyaasha hawlgalka isku-dhafan, waxa loo qaybin karaa qaybahan soo socda.
1, ujeedo-guud: cod-weyneeye hawleedka ujeeddada guud waxa loo qaabeeyey ujeedooyin guud.Habka ugu muhiimsan ee qalabka noocan oo kale ah waa qiimaha hooseeya, tiro badan oo alaab ah, iyo tilmaamayaasha waxqabadkoodu waxay ku haboonaan karaan isticmaalka guud.Tusaale μA741 (hal op-amp), LM358 (dual op-amps), LM324 (afar op-amps), iyo tuubbada saameeynta goobta sida heerka gelinta ee LF356 waa sidaas.Hadda waa cod-weyneyaasha hawlgalka isku-dhafan ee inta badan la isticmaalo.
2, Nooca iska caabinta Sare
Noocan cod-weyneeye-hawleed isku-dhafan waxa lagu gartaa hab-soo-gelinta hab-dhismeed aad u sarreeya iyo xag-jir wax-gelineed oo aad u yar, guud ahaan ka takhalus>1GΩ~1TΩ, oo leh IB dhowr picoamps ilaa tobanaan picoamps.Cabbirka ugu weyn ee lagu gaarayo yoolalkan waa in la isticmaalo sifooyinka hor-istaaga sare ee FET-yada si loo sameeyo heerka wax-gelinta kala duwan ee op-amp.Iyada oo FET ay tahay heerka wax gelinta, ma aha oo kaliya is-hortaagga wax-soo-gelinta sare, eexda wax-gelinta hoose ee hadda, iyo faa'iidooyinka xawaaraha sare, ballaadhanaanta, iyo qaylada hoose, laakiin korantada wax-is-gelinta ayaa weyn.Aaladaha isku dhafan ee caadiga ah waa LF355, LF347 (afar op-amps), iyo wax-is-gelinta sare CA3130, CA3140, iwm. [2]
3, Nooca qulqulaya heerkul-hoose
Qalabka saxda ah, ogaanshaha calaamadaha daciifka ah, iyo qalabka kale ee kantaroolka tooska ah, waxaa had iyo jeer la rabaa in korantada op-amp's detuning ay noqoto mid yar oo aan isbeddelin heerkulka.Heerkulka hoose ee cod-weyneyaasha shaqada ayaa loo qaabeeyey ujeedadan.OP07, OP27, AD508, iyo ICL7650, qalab-chopper-dejin-dejin-hooseeya oo ka kooban MOSFETs, waa qaar ka mid ah saxan-sare, heer-kulka-hooseeya cod-weyneyaasha hawlgalka ee maanta la isticmaalo.
4, Nooca xawaaraha sare leh
Si degdeg ah A/D iyo D/A beddelayaasha iyo cod-weyneyaasha fiidiyowga, heerka beddelka SR ee isku-dhafka op-amp waa inuu ahaadaa mid sarreeya iyo faa'iidada faa'iidada midnimada ee BWG waa inay ahaataa mid weyn oo ku filan sida op-amps isku-dhafan ee ujeeddo guud aysan ku habboonayn. codsiyada xawaaraha sare leh.Op-amps-xawaaraha sarreeya waxaa inta badan lagu gartaa heerarka beddelka sare iyo jawaabta soo noqnoqoshada ballaaran.Op-amp-yada caadiga ah waa LM318, μA715, iwm., kuwaas oo SR=50~70V/annaga, BWG>20MHz.
5,Nooca isticmaalka tamarta hoose.
Sida faa'iidada ugu weyn ee wareegga elektiroonigga ah, is-dhexgalka ayaa ah in la sameeyo wareegyo adag oo yaryar oo fudud, sidaas darteed ballaarinta kala duwanaanta codsiga ee qalabka la qaadi karo, waxaa lagama maarmaan ah in la isticmaalo koronto yar oo koronto ah, isticmaalka tamarta yar ee wajiga cod-weyneeye ee lagu dabaqi karo.Amplifiers-ka caadiga ah ee la isticmaalo waa TL-022C, TL-060C, iwm, kuwaas oo danabkoodu yahay ± 2V ~ ± 18V, isticmaalka hadda waa 50 ~ 250μA.Alaabooyinka qaarkood waxay gaareen heerka μW, tusaale ahaan, korontada ICL7600 waa 1.5V, isticmaalka korontadu waa 10mW, kaas oo lagu shaqeyn karo hal batari.
6, danab sare iyo noocyada awoodda sare
Korontada wax-soo-saarka ee amplifiers-hawleed waxay inta badan xaddidan tahay korontadu.Cod-weyneyaasha hawlgalka caadiga ah, korantada wax-soo-saarka ugu badan ayaa caadiyan ah dhawr tobnaad oo volts iyo hadda wax-soo-saarku waa dhawr iyo toban milliamps.Si loo kordhiyo korantada wax soo saarka ama si loo kordhiyo wax soo saarka hadda, op-amp isku dhafan waa in dibadda lagu kabo wareegga caawiye.Danab sare iyo op-yada isku-dhafan ee hadda sarreeya waxay soo saari karaan danab sare iyo hadda sare iyada oo aan wax wareeg ah oo dheeraad ah la helin.Tusaale ahaan, D41 isku-dhafan op-amp waxay keeni kartaa koronto ilaa ± 150V iyo μA791 isku-dhafan op-amp waxay keeni kartaa qulqulka wax soo saarka ilaa 1A.
7,Nooca kontoroolka la barnaamiji karo
Habka qalabaynta, waxaa jira dhibaato kala duwan.Si loo helo koronto go'an oo go'an, waxaa lagama maarmaan ah in la beddelo kor u qaadida cod-weyneeye hawleedka.Tusaale ahaan cod-weyneeye-hawleedku waxa uu leeyahay 10-jeer, marka signal-ku-gudbigu yahay 1mv, korantada wax-soo-saarku waa 10mv, marka tamarta wax-soo-saarka ahi tahay 0.1mv, wax-soo-saarku waa 1mv oo keliya, si loo helo 10mv, weynaynta waa in ay noqotaa loo beddelay 100. Tusaale ahaan, PGA103A, iyadoo la xakameynayo heerka pin 1,2 si loo beddelo cod-weyneysiinta.
