Xov Xwm Kev Lag Luam: Transistor yog dab tsi

Hom Transistors

Ob hom transistors yooj yim yog bipolar junction transistor thiab field effect transistor. Cov BJTs muaj, ntawm ob hom yooj yim: NPN thiab PNP, ob lub charge carriers-yog electrons lossis qhov. FETs feem ntau siv ib hom lossis lwm hom charge carriers thiab tuaj ntau yam xws li JFET thiab MOSFET.

Yuav ua li cas Transistors Ua Haujlwm

Cov transistors ua haujlwm los ntawm kev tswj cov hluav taws xob ntws los ntawm cov khoom siv semiconductor. Hauv BJT, cov dej ntws tawm ntawm thaj chaw puag ncig tswj cov dej ntws ntawm cov emitter thiab collector. Txawm li cas los xij hauv FET, nws cuam tshuam nrog kev coj ntawm cov channel ntawm qhov chaw thiab collector, qhov twg cov yeeb nkab ntws tau siv los ntawm kev siv lub zog hluav taws xob ntawm qhov kawg ntawm lub rooj vag.

Cov Cheebtsam Tseem Ceeb ntawm Transistor

Cov khoom tseem ceeb ntawm lub transistor nyob ntawm nws hom; rau BJT cov no suav nrog emitter, base, collector thiab collector/emitter ua ke thaum nyob hauv FET muaj peb lub hauv paus - qhov dej ntws ntawm qhov rooj. Ua ke cov no ua haujlwm los tswj cov dej ntws tam sim no uas tso cai rau nws ua qhov hloov pauv lossis ua kom muaj zog ntawm nws tus kheej.

Kev ua kom nrov dua hauv cov khoom siv suab

Hais txog kev siv tshuab suab, kev ua kom lub suab nrov dua yog ib qho ntawm cov cheeb tsam tseem ceeb uas tswj hwm los ntawm cov transistors. Txawm tias nws yog lub teeb tsa portable rau lub suab zoo stereo IR, cov transistors ua haujlwm los ntes cov teeb liab hluav taws xob tsis muaj zog, ua kom lawv nrov dua, thiab siv lawv ua cov suab tso tawm. Kev siv zoo li no muab kev pab txo qis ntawm kev cuam tshuam uas kev tsim suab tau ua rau nws tus kheej tsis zoo hauv ntau qhov kev hnov ​​​​​​suab nrov.

Kev tswj hwm lub zog hauv kev siv hluav taws xob

Cov transistors yog cov khoom tseem ceeb hauv cov voj voog tswj fais fab, ua kom cov khoom siv hluav taws xob tau txais cov qib voltage thiab tam sim no raws li xav tau. Ua zoo li cov keyboards lossis cov resistors hloov pauv tau, lawv tswj cov hluav taws xob kom tsim kom muaj kev sib npaug thiab ruaj khov, tiv thaiv cov khoom rhiab heev thaum ua kom zoo dua qub hauv ntau yam khoom siv hluav taws xob.

Kev sib hloov thiab kev sib txuas lus logic

Cov khoom siv hluav taws xob digital vam khom cov transistors ua lub hauv paus ntawm kev hloov pauv thiab cov voj voog logic, uas hloov pauv sai sai ntawm cov xeev qhib / kaw uas sawv cev rau binary 0s / 1s - tseem ceeb hauv txhua qhov kev suav suav txij li cov tshuab xam zauv yooj yim mus rau cov kab ke computer nyuaj. Transistors hauv cov voj voog logic ua rau cov khoom siv hluav taws xob ua tiav cov ntaub ntawv tau zoo dua thaum txiav txim siab sai dua.

Cov khoom siv sib txuas lus wireless

Kev siv cov transistors tshwj xeeb yog hais txog kev ua kom nrov dua, hloov kho, thiab demodulating cov teeb liab hauv cov khoom siv nrov xws li smartphones, Wi-Fi routers, thiab cov kab ke sib txuas lus satellite. Lawv cov yam ntxwv ntawm kev tswj cov teeb liab zaus siab kuj txhais tau tias lawv yog cov neeg tseem ceeb ntawm kev sib txuas wireless uas peb niaj hnub no vam khom.

Kev Cuam Tshuam ntawm Transistors rau Kev Txhim Kho Kev Siv Tshuab

Nrog lawv txoj kev tsim kho thiab kev txhim kho, cov transistors tau cuam tshuam loj heev rau thev naus laus zis, muab rau lwm tus nrog ntau yam kev lag luam uas tau hloov pauv mus rau hauv ib lub ntiaj teb niaj hnub raws li peb paub nws.

Kev Hloov Pauv Tshiab ntawm Kev Siv Computer

Cov transistors tau ua rau nws muaj peev xwm rau cov thev naus laus zis computer hla dhau theem tseem ceeb ntawm kev hloov pauv. Lub caij nyoog ntawm cov khoos phis tawj xws li cov khoos phis tawj tus kheej, laptops, thiab cov xov tooj ntse muaj zog, uas peb nqa hauv peb lub hnab ris tau yooj yim, tau los tom qab transistors hloov lub raj nqus tsev loj, qeeb uas tsis tuaj yeem haum rau hauv txhua yam me me.

Siv Tau Cov Khoom Siv Hluav Taws Xob Uas Nqa Tau

Qhov me me thiab siv hluav taws xob tsawg ntawm cov transistors yog li ua rau muaj kev tsim cov khoom siv hluav taws xob nqa tau. Txij li cov tshuab xam zauv nqa tau mus rau cov neeg ua si suab paj nruag nqa tau thiab cov khoom siv niaj hnub no, cov transistors tau yog lub hauv paus tseem ceeb ntawm kev ua kom me me thiab kev yooj yim nqa tau ntawm cov khoom siv hluav taws xob.

Kev Txhim Kho Kev Sib Txuas Lus

Cov transistors tau pab txhawb kev sib txuas lus, xws li kev tsim cov khoom siv sib txuas lus me me thiab ua haujlwm tau zoo dua los ntawm xov tooj ntawm tes mus rau cov kab ke satellite. Kev ua thiab xa cov teeb liab ntawm qhov ceev thiab kev ntseeg tau ntau dua tau hloov pauv txoj kev sib txuas lus thoob ntiaj teb.

Kev Txhim Kho Kev Siv Hluav Taws Xob Zoo

Kev txhim kho tas mus li ntawm cov thev naus laus zis transistor tau ua rau muaj kev txuag hluav taws xob. Cov transistors niaj hnub no siv hluav taws xob tsawg dua piv txwv li khiav cov kab ke sai dua, uas txhais tau tias cov khoom siv txuag hluav taws xob. Qhov no tsis yog tsuas yog ua rau cov thev naus laus zis tsis ua rau muaj kev puas tsuaj rau ib puag ncig xwb tab sis kuj tau pab kom lub roj teeb siv tau ntev dua hauv cov khoom siv nqa tau.
