Qhov txawv ntawm N-channel MOSFET thiab P-channel MOSFET! Pab koj xaiv MOSFET cov tuam txhab zoo dua!

Cov neeg tsim hluav taws xob Circuit Court yuav tsum tau xav txog cov lus nug thaum xaiv MOSFETs: Puas yog lawv xaiv P-channel MOSFET lossis N-channel MOSFET? Raws li cov chaw tsim khoom, koj yuav tsum xav kom koj cov khoom sib tw nrog lwm tus tub lag luam ntawm tus nqi qis, thiab koj kuj yuav tsum ua kom rov sib piv. Yog li yuav xaiv li cas? OLUKEY, lub chaw tsim khoom MOSFET nrog 20 xyoo ntawm kev paub, xav qhia rau koj.

Qhov txawv 1: conduction yam ntxwv

Cov yam ntxwv ntawm N-channel MOS yog tias nws yuav qhib thaum Vgs ntau dua li tus nqi. Nws yog tsim rau siv thaum lub hauv paus yog grounded (tsawg-kawg tsav), tsuav yog lub rooj vag voltage mus txog 4V los yog 10V. Raws li rau cov yam ntxwv ntawm P-channel MOS, nws yuav tig rau thaum Vgs tsawg dua ib qho nqi, uas yog tsim rau cov xwm txheej thaum lub hauv paus txuas nrog VCC (high-end drive).

Qhov txawv 2:MOSFEThloov poob

Txawm hais tias nws yog N-channel MOS lossis P-channel MOS, muaj kev tiv thaiv tom qab nws qhib, yog li tam sim no yuav siv lub zog ntawm qhov kev tawm tsam no. Qhov no ntawm lub zog noj yog hu ua conduction poob. Xaiv MOSFET nrog ib qho me me ntawm kev ua haujlwm yuav txo qhov kev poob qis, thiab qhov kev tawm tsam ntawm MOSFETs tam sim no tsis muaj zog yog feem ntau nyob ib ncig ntawm kaum ntawm milliohms, thiab tseem muaj ntau milliohms. Tsis tas li ntawd, thaum MOS qhib thiab tawm, nws yuav tsum tsis txhob ua kom tiav tam sim ntawd. Muaj cov txheej txheem txo qis, thiab cov dej ntws tam sim no kuj muaj cov txheej txheem nce ntxiv.

Lub sijhawm no, MOSFET qhov poob yog qhov khoom ntawm qhov hluav taws xob thiab qhov tam sim no, hu ua hloov pauv poob. Feem ntau hloov pauv qhov poob yog qhov loj dua qhov kev poob qis, thiab qhov siab dua qhov hloov zaus, qhov poob ntau dua. Cov khoom ntawm qhov voltage thiab tam sim no nyob rau hauv lub sij hawm ntawm conduction yog heev loj, thiab qhov poob tshwm sim kuj loj heev, yog li shortening lub sij hawm hloov yuav txo tau qhov poob thaum lub sij hawm txhua conduction; txo qhov hloov zaus tuaj yeem txo tus naj npawb ntawm cov keyboards ib lub sijhawm.

Qhov sib txawv peb: MOSFET siv

Lub qhov txav ntawm P-channel MOSFET yog qhov tsawg, yog li thaum lub geometric loj ntawm MOSFET thiab tus nqi ntawm kev khiav hauj lwm voltage yog sib npaug, qhov transconductance ntawm P-channel MOSFET yog me dua li ntawm N-channel MOSFET. Tsis tas li ntawd, tus nqi ntawm qhov pib voltage ntawm P-channel MOSFET yog qhov siab, yuav tsum muaj kev ua haujlwm siab dua. P-channel MOS muaj lub logic viav vias loj, kev them nyiaj ntev thiab kev tso tawm, thiab cov khoom siv me me transconductance, yog li nws cov kev khiav hauj lwm ceev qis dua. Tom qab qhov tshwm sim ntawm N-channel MOSFET, feem ntau ntawm lawv tau hloov los ntawm N-channel MOSFET. Txawm li cas los xij, vim tias P-channel MOSFET muaj cov txheej txheem yooj yim thiab pheej yig, qee qhov nruab nrab thiab me me digital tswj circuits tseem siv PMOS circuit technology.

Okay, yog txhua yam rau hnub no kev sib koom los ntawm OLUKEY, lub chaw tsim khoom ntim MOSFET. Yog xav paub ntxiv, koj tuaj yeem nrhiav peb ntawmOLUKEYofficial lub website. OLUKEY tau tsom mus rau MOSFET rau 20 xyoo thiab yog lub hauv paus hauv Shenzhen, Guangdong Province, Suav. Feem ntau koom nrog cov txiaj ntsig tam sim no, lub zog siab MOSFETs, pob loj MOSFETs, me me voltage MOSFETs, me me pob MOSFETs, me me tam sim no MOSFETs, MOS teb nyhuv hlab, ntim MOSFETs, hwj chim MOS, MOSFET tej pob khoom, thawj MOSFETs, ntim MOSFETs, thiab lwm yam .
