Pendahuluuan
Lub transistor tej zaum yog ib qho ntawm cov khoom tsim tseem ceeb tshaj plaws ntawm lub xyoo pua 20th, uas tau hloov pauv lub ntiaj teb ntawm kev siv tshuab. Nws tsis yog tsuas yog ib qho tseem ceeb hauv ntau yam khoom siv hluav taws xob xwb, tab sis nws kuj tau tsav kev tsim kho tshiab hauv ntau yam kev siv tshuab thiab kev tshawb fawb. Tsab xov xwm no yuav tham txog qhov tob txog lub transistor yog dab tsi, nws keeb kwm, nws ua haujlwm li cas, thiab nws qhov cuam tshuam rau kev txhim kho ntawm cov thev naus laus zis niaj hnub no.
Transistor yog dab tsi?
Hais yooj yim xwb, lub transistor yog ib qho khoom siv semiconductor siv los tswj cov hluav taws xob tam sim no. Lub transistor muaj ob lub luag haujlwm tseem ceeb: ua lub qhov hloov lossis lub amplifier. Hauv kev siv hloov pauv, lub transistor tuaj yeem qhib lossis kaw qhov ntws ntawm cov hluav taws xob tam sim no. Ua lub amplifier, lub transistor tuaj yeem ua kom lub teeb liab hluav taws xob tuaj loj dua.
Keeb Kwm ntawm Transistors
Ua ntej tsim tau lub transistor, cov raj nqus tsev tau siv dav hauv cov khoom siv hluav taws xob. Txawm li cas los xij, cov raj nqus tsev muaj qhov tsis zoo: lawv loj, yooj yim ua kom sov, thiab tsis ua haujlwm zoo. Yog li ntawd, cov kws tshawb fawb tau pib nrhiav cov kev daws teeb meem zoo dua thiab siv tau zoo dua.
Xyoo 1947, peb tug kws tshawb fawb los ntawm Bell Laboratories—John Bardeen, Walter Brattain, thiab William Shockley—tau tsim thawj lub transistor. Qhov kev tshawb pom no yog qhov tshwm sim ntawm kev tshawb fawb ntau yam txog cov khoom ntawm semiconductors. Rau qhov kev ua tiav no, lawv tau txais khoom plig Nobel hauv Physics xyoo 1956.
Hom Transistors
1. Bipolar Transistor (Bipolar Junction Transistor/BJT):
Muaj ob hom, NPN thiab PNP, cov transistors no ua haujlwm raws li qhov ntws ntawm cov hluav taws xob los ntawm lub hauv paus mus rau lub emitter. BJTs feem ntau yog siv rau hauv cov ntawv thov amplification vim lawv muaj peev xwm muab cov hluav taws xob siab dua.
2. Transistor Field-Effect (FET):
Tsis zoo li BJTs, FETs tswj cov dej ntws tam sim no los ntawm lub teb hluav taws xob. Hom FET feem ntau yog MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor), uas yog siv dav hauv cov voj voog digital thiab cov khoos phis tawj.
Txoj Cai Ua Haujlwm ntawm Transistor
1. Bipolar Transistor (BJT):
Hauv BJT, muaj peb txheej semiconductor: emitter, base, thiab collector. Hauv NPN transistor, thaum muaj hluav taws xob me me rau ntawm lub base, hluav taws xob ntws los ntawm emitter mus rau lub base thiab tom qab ntawd mus rau collector. Cov txheej txheem no tso cai rau transistor 'tig' lossis 'tua' hluav taws xob loj dua.
2. Transistor Teb (FET):
Ib tug FET muaj peb lub qhov kawg: qhov chaw, lub rooj vag, thiab qhov dej ntws. Thaum lub zog hluav taws xob raug siv rau lub rooj vag, lub zog hluav taws xob tshwm sim tswj cov dej ntws ntawm qhov chaw thiab qhov dej ntws. Qhov no ua rau FETs ua haujlwm tau zoo dua hauv cov ntawv thov uas siv hluav taws xob tsawg.
Kev Siv Transistors Hauv Kev Siv Tshuab Niaj Hnub
1. Cov Khoos Phis Tawj thiab Cov Microprocessors:
Cov transistors yog ib qho tseem ceeb hauv kev tsim cov microprocessors niaj hnub no. Ib lub microprocessor niaj hnub no muaj peev xwm muaj ntau txhiab lab transistors uas ua haujlwm ua microswitches los ua cov lus qhia txog kev xav, ua rau lub khoos phis tawj ua cov haujlwm nyuaj sai thiab zoo.
2. Kev Sib Txuas Lus Hauv Xov Tooj:
Cov xov tooj ntse uas peb siv txhua hnub kuj vam khom ntau rau cov transistors hauv lawv cov chips rau kev ua cov ntaub ntawv, kev ua kom lub teeb liab nrov dua, thiab ntau yam haujlwm. Yog tsis muaj transistors, qhov me me thiab kev ua haujlwm zoo uas ua rau cov xov tooj ntse ua tau yuav tsis ua tau.
3. Cov Khoom Siv Hluav Taws Xob Rau Cov Neeg Siv Khoom:
Cov khoom xws li TV, xov tooj cua, thiab cov khoom siv suab siv cov transistors rau kev ua cov cim thiab kev ua kom nrov dua. Hauv cov khoom siv suab, cov transistors siv rau hauv cov amplifiers los muab lub suab meej thiab muaj zog.
4. Kev Lag Luam Tsheb:
Cov tsheb niaj hnub nim no muaj cov khoom siv hluav taws xob transistorized, los ntawm cov tshuab infotainment mus rau kev tswj cav thiab cov tshuab tswj pa phem.
5. Cov Khoom Siv Kho Mob:
Cov khoom siv kho mob xws li cov ntsuas lub plawv thiab lwm yam khoom siv kuaj mob siv cov transistors los xyuas kom meej tias muaj kev ua haujlwm zoo thiab raug.
Yav Tom Ntej ntawm Transistors
Nrog kev nce qib ntawm thev naus laus zis, cov transistors txuas ntxiv tsim kho tshiab hauv qhov loj me thiab kev ua tau zoo. Ib qho tseem ceeb yog kev ua kom me me los ntawm kev siv tshuab nanometer, uas tso cai rau ntau cov transistors kom muab tso rau ntawm ib lub chip yam tsis ua rau qhov loj ntawm lub chip nws tus kheej nce ntxiv.
Kev tshawb fawb kuj tseem tab tom ua nyob rau hauv cov ntaub ntawv semiconductor tshiab xws li graphene thiab molybdenum disulfide, uas yuav muab kev ceev dua thiab kev siv hluav taws xob zoo dua piv rau silicon ib txwm muaj.
Tsis tas li ntawd xwb, cov khoos phis tawj quantum yog ib qho chaw uas cov transistors ib txwm muaj yuav raug hloov los ntawm qubits, cov chav nyob yooj yim hauv kev suav lej quantum, tab sis cov transistors tseem yuav ua lub luag haujlwm tseem ceeb hauv kev tswj thiab ntsuas lub xeev ntawm cov qubits ntawd.
Kev kaw
Cov transistors tsis yog tsuas yog cov khoom me me hauv cov hluav taws xob xwb; lawv yog lub hauv paus ntawm cov thev naus laus zis niaj hnub no uas peb nyiam siv niaj hnub no. Txij li cov khoos phis tawj mus rau cov khoom siv kho mob thiab cov xov tooj ntse, cov transistors ua lub luag haujlwm tseem ceeb thiab dav dav. Raws li cov khoom uas tswj cov hluav taws xob ntws, cov transistors tau qhib lub qhov rooj rau ntau yam kev tsim kho tshiab thiab ua rau muaj kev nce qib hauv kev siv tshuab hauv ntau qhov chaw.
Nrog kev tshawb pom thiab kev tsim kho tshiab tas li, lub neej yav tom ntej ntawm transistor zoo li ci ntsa iab ib yam li yav dhau los. Kev tshawb fawb tshiab thiab cov ntaub ntawv tshiab yuav txuas ntxiv thawb cov ciam teb ntawm qhov ua tau, kom ntseeg tau tias cov transistors tseem yog ib feem tseem ceeb ntawm peb lub ntiaj teb thev naus laus zis.
