Lub transistor yog ib qho khoom tsim los ua kom nrov, tsim, thiab hloov hluav taws xob oscillations. Muaj ob hom transistors: bipolar thiab field effect.

Lub tshuab hluav taws xob bipolar yog cov khoom siv semiconductor uas muaj ob lub p-n junctions. Lub hauv paus transistor yog tsim los ntawm germanium siv lead ua, nws muaj ob lub tswv yim: ib qho emitter thiab ib tug collector, uas kov lub crystal nto, sib cais los ntawm ib tug deb ntawm 20-50 microns. Hauv lwm lo lus, ib qho kev sib txuas txuas cov emitter mus rau hauv paus (hu ua emitter junction), thiab qhov thib ob txuas tus neeg sau rau hauv lub hauv paus (hu ua kev sib tshuam sib txuas). Bipolar transistors muab faib ua ob hom: p-n-p thiab n-p-n.

FET yog cov khoom siv hluav taws xob semiconductor uas tswj hwm los ntawm kev hloov pauv hauv thaj teb, tsis zoo li bipolar cov ntsiab lus, qhov tso tawm tus nqi tam sim no txiav txim siab los ntawm kev hloov pauv ntawm cov khoom tam sim no. Cov cuab yeej teb muaj nyob rau hauv ib lub rooj vag thiab ntau qhov rooj tsim.

Daim duab kab hluav taws xob ntawm lub transistor tau qhia hauv daim duab hauv qab no. Lub tswv yim ntawm lub ntsiab lus bipolar yog ib txoj kab luv luv, nws cim lub hauv paus, uas yog ob txoj kab inclined nkag rau ntawm lub kaum sab xis ntawm 60 0 thiab 120 0, kab nrogtus xub yog tus emitter, qhov thib ob yog tus sau. Cov kev taw qhia ntawm tus xub qhia txog yam khoom siv. Lub xub taw rau lub hauv paus yog p-n-p hom transistor, los ntawm lub hauv paus - n-p-n.

Txoj kab perpendicular rau hauv paus yog lub hauv paus electrode. Tus nqi ntawm cov conductivity ntawm lub emitter yuav tsum paub txog qhov tseeb kev twb kev txuas ntawm lub transistor rau lub hwj chim qhov chaw. Cov khoom siv ntawm p-n-p hom yuav tsum tau muab qhov tsis zoo ntawm qhov transistor rau cov khoom siv thiab lub hauv paus, thiab hom n-p-n yuav tsum yog qhov zoo. Field-effect transistors nyob rau hauv daim duab qhia raws li nram no: nws yog kev cai los qhia lub rooj vag nrog ib tug khiav ceev thaum uas tig mus rau lub channel cim, cov hluav taws xob conductivity ntawm cov channel yog depicted los ntawm ib tug xub muab tso rau ntawm qhov chaw thiab ntws. Yog hais tias tus xub taw qhia nyob rau hauv cov kev taw qhia ntawm lub channel, ces qhov no txhais tau hais tias lub caij belongs rau n-hom, thiab yog hais tias nyob rau hauv lub opposite kev taw qhia, ces lub p-hom. Daim duab ntawm lub teb cuam tshuam transistor nrog ib qho induction channel yog txawv los ntawm peb lub luv luv strokes. Yog hais tias lub teb ntaus ntawv muaj ob peb lub rooj vag, lawv pom raws li ib tug luv luv dashes, kab ntawm thawj lub rooj vag yog ib txwm muab tso rau ntawm qhov txuas ntxiv ntawm qhov chaw kab.

Nyob rau hauv xaus, peb ntxiv hais tias xws li lub npe tsis tau muab tam sim ntawd rau transistors, lawv yog Ameslikas hu ua semiconductor triodes (zoo ib yam li lub teeb technology). Yog li ntawd, lub transistor yog ib tug triode, uas yog ib tug tswj lub caij, nws yog dav siv nyob rau hauv mem tes thiab amplifying circuits. Tsis muaj cua sov, kev ntseeg siab, me me tag nrho qhov ntev thiab tus nqi - cov no yog qhov zoo ntawm cov khoom siv no, ua tsaug rau cov transistors.muaj peev xwm tshem tau cov raj xa hluav taws xob los ntawm ntau ceg ntawm kev siv tshuab. Lub ntsiab kom zoo dua ntawm cov khoom siv semiconductor yog qhov tsis muaj cov cathode incandescent, uas siv lub zog tseem ceeb thiab tseem siv sijhawm los ua kom sov. Tsis tas li ntawd, lub transistor yog ntau zaus me dua li lub teeb hluav taws xob thiab muaj peev xwm ua haujlwm ntawm qhov hluav taws xob qis. Tag nrho cov no ua rau nws muaj peev xwm txo tau qhov ntev ntawm cov khoom siv hluav taws xob.
