Analoogga beddelka
Theanaloog(amaPETR)beddelo, sidoo kale loo yaqaanwareeg laba geesood ah, waa ahelegtaroonig ahqayb u dhaqma si la mid ah agudbin, laakiin ma lehqaybaha dhaqaaqa.Cunsurka beddelka ayaa caadiyan ah labo ka mid ahMOSFET transistors, mid waa N-channel, kan kalena P-channel.Qalabku wuxuu u samayn karaa calaamadaha analoogga ama dhijitaalka ah labada dhinac marka uu shido oo wuxuu go'doomiyaa terminaalka damiyay marka uu dansan yahay.Furayaasha analooga ah waxaa badanaa loo soo saaraa sidawareegyada isku dhafanbaakado ay ku jiraan furayaal badan (sida caadiga ah laba, afar ama siddeed).Kuwaas waxaa ka mid ah 4016 iyo 4066 ka4000 taxane.
Gelitaanka kontoroolka ee aaladda ayaa laga yaabaa inay noqoto calaamad u kala wareegta tamarta sahayda togan iyo kuwa taban, iyadoo korantada togan ee aaladda ay shideyso iyo daminta aaladda.Wareegyada kale waxaa loogu talagalay in lagu wada xiriiro iyada oo la marayo deked taxane ah oo leh koontaroolaha martida loo yahay si loo damiyo ama loo damiyo.
Digniinta la shiday waa in ay ku sii jirtaa xudduudaha biraha saadka ee togan iyo kuwa taban ee ku xiran P-MOS iyo N-MOS terminaalka jirka.Dareewalka guud ahaan wuxuu bixiyaa go'doomin wanaagsan oo u dhexeeya calaamada kontoroolka iyo calaamadaha wax-gelinta/soo-saarka.Looma isticmaalo beddelidda danab sare.
Halbeegyada muhiimka ah ee beddelka analoogga waa:
- on-resistance: caabbinta marka shid.Tani waxay caadi ahaan u dhaxaysaa 5ohmsilaa dhowr boqol oo ohms.
- off-resistance: caabbinta marka la damiyo.Tani caadi ahaan waa tiro megaohms ama gigaohms ah.
- kala duwanaanshaha calaamadaha: ugu yaraan iyo ugu badnaan danabka loo oggol yahay in calaamadda la dhex maro.Haddii kuwan la dhaafo, beddelka waxaa laga yaabaa inuu burburiyo qulqulka xad dhaafka ah.Noocyadii hore ee furayaasha ayaa xitaa karaqabsato, taas oo macnaheedu yahay inay sii wadaan inay sameeyaan qulqulo xad-dhaaf ah xitaa ka dib marka calaamadda khaldan la saaro.
- lacag duritaan.Saamayntani waxay keentaa in beddelka uu ku duro wax yarkharash korontodhexda calaamadda marka ay shidto, taasoo keenaysa mid yarbaraarujinamacilad.Duritaan qarashka ayaa lagu qeexaycoulombs.
Furayaasha analooga ah ayaa laga heli karaa labadabatignoolajiyada daloolama bytignoolajiyada korka-korkabaakadaha.
Dareemaha analoogga ah waa furaha adeegsada sifooyinka JFET ama MOS si loo xakameeyo jidka calaamadda.
Shidaalka analoogga ah waa furaha la isticmaalosifooyinka JFETamaMOSsi loo xakameeyo jidka ishaarada, waxaana inta badan loo isticmaalaa in lagu dhamaystiro shaqada beddelka ee xidhiidhka signalka ama goynta.Sababtoo ah isticmaalka tamarta hooseeya, xawaaraha degdega ah, ma jiro xiriirin farsamo, cabbir yar iyo nolol dheer oo adeeg ah, waxaa si ballaaran loo adeegsaday nidaamyada xakamaynta tooska ah ee kala duwan iyo alaabada dhijitaalka ah ee elektiroonigga ah.
Qaab-dhismeedka hab-socodka CMOS-dhaqameedka is-beddelka analoogga waxa lagu muujiyey Jaantuska 1. Isku-xidhka NMOS iyo PMOS ee isbar-bar yaacaya waxay u oggolaanaysaa calaamaduhu inay si siman ugu gudbaan labada dhinac.Albaabka waxa loo isticmaalaa in lagu xakameeyo shidista iyo daminta furaha.NMOS waxay shidaysaa marka Vgs-ku togan yahay, oo dami marka Vgs-ku xumaado, PMOS-na wuxuu sameeyaa caksigeeda.Sababo la xiriira sifooyinka kala duwan ee PMOS iyo NMOS, beddelka ka kooban iyaga ayaa leh sifooyinka lagu muujiyey shaxanka hoose.Qadarka calaamadda hadda jirta ee u dhaxaysa NMOS iyo PMOS waxaa lagu go'aamiyaa saamiga gelinta iyo danab soo-saarka.Maaddaama dareeshka uusan lahayn dhibaatada xulashada jihada socodka hadda, ma jirto wax farqi ah oo u dhexeeya soo-gelinta iyo soo-saarka.Labada MOSFET waa la shiday ama waa la damiyay iyadoo ay gacanta ku hayaan caqli-celinta gudaha iyo kuwa aan leexin.Faa'iidada furayaasha CMOS waa kala duwanaanshaha firfircoonida tareen-ilaa-tareenka, hawlgalka laba jiho, iyo iska caabintu isma beddesho marka korantada wax gelinta ahi is beddesho.
