MOSFET Xaiv | N-Channel MOSFET Kev Tsim Kho Cov Cai

Hlau-Oxide-SemIConductor qauv ntawm crystal transistor feem ntau hu uaMOSFET, qhov twg MOSFETs muab faib ua P-hom MOSFETs thiab N-hom MOSFETs. Kev sib xyaw ua ke ntawm MOSFETs kuj tseem hu ua MOSFET integrated circuits, thiab cov kev sib raug zoo ntawm MOSFET integrated circuits tsim los ntawm PMOSFETs thiabNMOSFETs yog hu ua CMOSFET integrated circuits.

Ib qho MOSFET uas muaj p-hom substrate thiab ob qhov chaw n-kis nrog cov txiaj ntsig siab yog hu ua n-channel.MOSFET, thiab cov conductive channel tshwm sim los ntawm ib tug n-hom conductive channel yog tshwm sim los ntawm cov n-txog txoj kev nyob rau hauv ob txoj kev n-tshwj xeeb nrog high concentration qhov tseem ceeb thaum lub raj conducts. n-channel thickened MOSFETs muaj cov n-channel tshwm sim los ntawm ib tug conductive channel thaum ib tug zoo taw qhia tsis ncaj ncees lawm ntau li ntau tau ntawm lub rooj vag thiab tsuas yog thaum lub rooj vag qhov chaw ua hauj lwm yuav tsum tau ib tug kev khiav hauj lwm voltage tshaj qhov pib voltage. n-channel depletion MOSFETs yog cov uas tsis tau npaj rau lub rooj vag voltage (qhov chaw ua haujlwm yuav tsum muaj kev khiav hauj lwm voltage ntawm xoom). Ib qho n-channel lub teeb depletion MOSFET yog n-channel MOSFET nyob rau hauv uas cov channel conductive tshwm sim thaum lub rooj vag voltage (lub rooj vag qhov kev khiav hauj lwm yuav tsum tau kev khiav hauj lwm voltage yog xoom) yog tsis npaj.

NMOSFET integrated circuits yog N-channel MOSFET fais fab mov Circuit Court, NMOSFET integrated circuits, input resistance yog siab heev, feem coob tsis tas yuav zom cov nqus ntawm lub zog khiav, thiab yog li CMOSFET thiab NMOSFET integrated circuits txuas yam tsis tas yuav coj mus rau hauv account lub load ntawm lub hwj chim txaus.NMOSFET integrated circuits, feem coob ntawm cov kev xaiv ntawm ib pab pawg neeg zoo switching zog cov khoom siv hluav taws xob hluav taws xob hluav taws xob feem ntau ntawm NMOSFET kev sib xyaw ua ke siv ib qho zoo hloov hluav taws xob hloov hluav taws xob hluav taws xob hluav taws xob hluav taws xob, thiab rau 9V rau ntau dua. CMOSFET integrated circuits tsuas yog yuav tsum tau siv tib lub zog hloov hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob raws li NMOSFET kev sib xyaw ua ke, tuaj yeem txuas nrog NMOSFET kev sib txuas tam sim. Txawm li cas los xij, los ntawm NMOSFET mus rau CMOSFET tam sim ntawd txuas nrog, vim tias NMOSFET cov zis tawm rub tawm yog tsawg dua li CMOSFET kev sib txuas hauv Circuit Court keyed rub-up, yog li sim siv qhov sib txawv ntawm qhov sib txawv rub-up resistor R, tus nqi ntawm tus resistor R yog. Feem ntau 2 txog 100KΩ.

Kev tsim kho ntawm N-channel thickened MOSFETs
Ntawm P-hom silicon substrate nrog tus nqi qis doping concentration, ob thaj tsam N nrog tus nqi siab doping concentration yog tsim, thiab ob lub electrodes raug rho tawm ntawm txhuas hlau los ua qhov ntws d thiab qhov chaw s, raws li.

Tom qab ntawd nyob rau hauv lub semiconductor tivthaiv nto npog ib tug nyias txheej ntawm silica insulating raj, nyob rau hauv lub ntws - qhov chaw insulating raj ntawm lub ntws thiab qhov chaw ntawm lwm txhuas electrode, raws li lub rooj vag g.

Nyob rau hauv lub substrate kuj coj tawm ib tug electrode B, uas muaj ib tug N-channel tuab MOSFET. MOSFET qhov chaw thiab substrate feem ntau txuas ua ke, feem ntau ntawm cov yeeb nkab hauv lub Hoobkas tau ntev txuas nrog nws, nws lub rooj vag thiab lwm cov electrodes yog insulated ntawm lub casing.
