Dab tsi yog qhov ua haujlwm ntawm transistor?

Lub hauv paus ntsiab lus ntawm transistors
Transistor, tseem hu ua semiconductor transistor, yog ib qho khoom siv hluav taws xob raws li cov khoom siv semiconductor xws li silicon lossis germanium, uas nws cov tub ntxhais yog lub peev xwm los tswj qhov ntws ntawm tam sim no. Piv nrog cov tshuab nqus tsev ib txwm muaj, cov khoom siv hluav taws xob muaj qhov zoo xws li qhov me me, kev siv hluav taws xob tsawg, lub neej ntev, thiab kev ntseeg siab. Lub hauv paus qauv ntawm ib tug transistor muaj xws li peb cheeb tsam: cheeb tsam emission, lub hauv paus cheeb tsam, thiab lub collector cheeb tsam. Los ntawm kev tswj cov tam sim no lossis qhov hluav taws xob hauv cheeb tsam hauv paus, nws muaj peev xwm ua tiav qhov kev hloov pauv tseem ceeb ntawm tam sim no los ntawm cheeb tsam emission mus rau cheeb tsam collector. Qhov peev xwm no ua rau lub transistor yog qhov tseem ceeb ntawm kev hloov pauv thiab cov khoom siv amplifier hauv hluav taws xob circuits.
Lub luag haujlwm tseem ceeb ntawm transistors
Amplification muaj nuj nqi: Ib qho ntawm cov haujlwm tseem ceeb tshaj plaws thiab tseem ceeb ntawm cov transistors yog kom ua kom cov teeb liab. Nyob rau hauv amplification circuits, transistors tuaj yeem ua kom lub zog hluav taws xob tsis muaj zog rau qib muaj zog txaus rau kev ua haujlwm txuas ntxiv lossis tsav tsheb. Cov nyhuv amplification no tsis txwv rau cov suab paj nruag, tab sis kuj suav nrog ntau hom teeb liab xws li video thiab xov tooj cua zaus. Nws yog ib qho ntawm cov thev naus laus zis tseem ceeb uas ua kom muaj kev sib txuas lus wireless, tshaj tawm, TV thiab lwm lub tshuab kom ua tiav.
Kev hloov pauv muaj nuj nqi: Los ntawm kev ua haujlwm ntawm transistor hauv thaj tsam saturation lossis txiav tawm, nws tuaj yeem siv los ua hluav taws xob hloov hluav taws xob siab. Nyob rau hauv digital circuits, transistors yog lub hauv paus tsev blocks ntawm logic rooj vag circuits, muaj peev xwm ua tau zoo xws li AND, LOSSIS, thiab TSIS, yog li tsim complex cov tshuab xws li computer processors thiab microcontrollers. Kev hloov pauv ceev ceev ntawm cov transistors ua rau cov circuits digital muaj qhov zoo xws li kev kub ceev, kev ua haujlwm zoo, thiab kev ua haujlwm, ua rau lawv lub hauv paus ntawm cov ntaub ntawv xov xwm niaj hnub no.
Kev tswj hluav taws xob thiab kev kho kom zoo: Hauv kev tswj hluav taws xob hluav taws xob, cov transistors tseem ua lub luag haujlwm tseem ceeb hauv kev tswj hluav taws xob thiab kev kho dua tshiab. Los ntawm kev tsim hluav taws xob tshwj xeeb, cov khoom siv hluav taws xob tuaj yeem ua kom ruaj khov ntawm qhov tso zis hluav taws xob thiab tiv thaiv lub nra ntawm qhov hloov pauv voltage; Nyob rau tib lub sijhawm, nws tseem tuaj yeem hloov AC lub zog rau hauv DC lub zog, muab lub zog DC ruaj khov rau ntau yam khoom siv hluav taws xob.
Kev hloov pauv ntau zaus thiab kev hloov pauv: Hauv kev sib txuas lus wireless, transistors tau dav siv rau kev hloov pauv zaus thiab teeb liab hloov. Los ntawm kev hloov cov kev tsis ncaj ncees thiab cov tswv yim tawm tswv yim ntawm cov transistors, zaus hloov pauv ntawm cov teeb liab (xws li zaus hloov pauv) tuaj yeem ua tiav, nrog rau kev hloov pauv ntawm cov teeb liab tsawg zaus mus rau cov neeg nqa khoom siab (xws li modulators), yog li ua tiav qhov ntev. kev xa xov xwm.
Qhov cuam tshuam ntawm Transistors rau Niaj hnub nimno Society
Kev txhim kho txuas ntxiv ntawm transistor thev naus laus zis tau txhawb nqa kev nce qib ntawm cov ntaub ntawv thev naus laus zis thiab txhawb nqa cov ntaub ntawv xov xwm thiab kev txawj ntse hauv zej zog. Nws ua rau cov khoos phis tawj txo qis los ntawm cov loj loj mus rau cov khoom siv nqa tau yooj yim, Internet tau nrov, thiab cov khoom siv ntse xws li cov xov tooj ntse thiab cov ntsiav tshuaj computers dhau los ua qhov tseem ceeb ntawm tib neeg lub neej niaj hnub. Hauv kev kho mob, transistor thev naus laus zis tau txhawb nqa qhov tseeb thiab kev txav mus los ntawm cov cuab yeej kho mob, txhim kho kev ua tau zoo thiab qhov tseeb ntawm kev kuaj mob thiab kev kho mob; Hauv kev lag luam kev lag luam, kev siv dav dav ntawm cov kab ntau lawm, cov neeg hlau ntse thiab lwm yam khoom siv yog sib cais los ntawm kev tswj hwm thiab cov ntaub ntawv muaj peev xwm ua tau los ntawm transistors.
