Bipolar transistor
Ib tug bipolar transistor yog hais txog ib tug transistor uas feem ntau siv nyob rau hauv lub suab circuits. Bipolar yog muab los ntawm kev sib raug zoo uas tam sim no ntws los ntawm ob yam khoom semiconductor. Lub bipolar transistor tuaj yeem muab faib ua hom NPN lossis PNP hom nyob ntawm qhov polarity ntawm kev khiav hauj lwm voltage.
Bipolar kev sib tshuam
"Bipolar" txhais tau hais tias ob qho tib si cov neeg nqa khoom, cov khoom siv hluav taws xob thiab lub qhov, koom nrog kev tawm suab tib lub sijhawm. Bipolar Junction Transistor (BJT), tseem hu ua semiconductor triode, yog ib qho khoom siv sib txuas ob PN junctions los ntawm ib qho txheej txheem. Muaj ob qhov kev sib txuas ntawm PNP thiab NPN; sab nraud coj peb tus ncej: Tus sau, emitter thiab lub hauv paus, lub collector yog coj tawm ntawm lub collector, lub emitter yog tshem tawm los ntawm lub emitter, thiab lub hauv paus yog muab tshem tawm los ntawm lub hauv paus (lub hauv paus yog nyob rau hauv nruab nrab); BJT muaj amplification, thiab nws nyob ntawm nws emitter tam sim no. Txhawm rau kom ntseeg tau tias cov txheej txheem kis no, txhawm rau kom ntseeg tau tias cov txheej txheem hloov pauv ntawm thaj chaw emitter yog qhov yuav tsum tau muaj ntau dua li cov neeg tawg loj dua ntawm thaj chaw, thiab cov thickness ntawm lub hauv paus cheeb tsam yog me me, thiab lwm yam Lub nam yuav tsum tau raws li cov sab nraud tej yam kev mob, uas yog, lub emitter hlws ris yuav tsum tau rau pem hauv ntej biased (ntxiv rau pem hauv ntej voltage), thiab lub collector hlws ris yuav tsum rov qab biased; muaj ntau hom BJT, raws li qhov zaus, muaj cov raj muaj ntau zaus, cov raj tsis tshua muaj, raws li cov ntsiab lus ntawm lub zog, muaj cov raj me me, nruab nrab thiab loj, raws li cov khoom siv semiconductor, muaj cov raj silicon thiab tantalum raj, thiab lwm yam. ; cov ntaub ntawv amplified Circuit Court yog: common emitter, common base thiab common collector amplifier circuit.
