Waba uzi icyo N-umuyoboro MOSFET aricyo?

I. Imiterere shingiro hamwe nibigize

Umuyoboro wa N-MOSFET ugizwe nibice byingenzi bikurikira:

Irembo:kugenzura itumanaho, muguhindura amarembo yumuryango kugirango ugenzure umuyoboro uyobora isoko nisoko.· ·

Inkomoko:Ibisohoka byubu, mubisanzwe bihujwe kuruhande rubi rwumuzingi.· ·

Umuyoboro: iyinjira ryubu, mubisanzwe bihujwe numutwaro wumuzunguruko.

Substrate:Mubisanzwe P-ubwoko bwa semiconductor ibikoresho, bikoreshwa nka substrate ya MOSFETs.

Imashini：Biri hagati y irembo numuyoboro, mubusanzwe bikozwe muri dioxyde ya silicon (SiO2) kandi ikora nka insulator.

II. Ihame ry'imikorere

Ihame ryimikorere ya N-umuyoboro MOSFET ishingiye ku ngaruka zamashanyarazi, igenda gutya:

Imiterere yo guhagarikwa:Iyo voltage yumuryango (Vgs) iri munsi yumubyigano (Vt), nta muyoboro wa N wo mu bwoko bwa N ukorwa muburyo bwa P-munsi yuburiri, bityo rero leta ikata hagati yisoko n'amazi iba ihari. n'ubu ntibishobora gutemba.

Imiterere yimyitwarire:Iyo amarembo yumuryango (Vgs) arenze hejuru yumubyigano (Vt), umwobo uri munsi yubwoko bwa P munsi yumuryango wongeye kwangwa, ugakora igabanuka. Hamwe no kwiyongera kwamashanyarazi yumuryango, electron zikururwa hejuru yubuso bwa P-substrate, bukora umuyoboro wa N-N. Kuri iyi ngingo, inzira yashizweho hagati yisoko n'amazi hamwe nibishobora gutemba.

III. Ubwoko n'ibiranga

N-umuyoboro MOSFETs urashobora gushyirwa mubwoko butandukanye ukurikije ibiranga, nka Enhancement-Mode na Depletion-Mode. Muri byo, Enhancement-Mode MOSFETs iri mubihe byaciwe mugihe voltage yumuryango ari zeru, kandi igomba gukoresha voltage nziza yumuryango kugirango ikore; mugihe Depletion-Mode MOSFETs yamaze kuba mumikorere iyo voltage yumuryango ari zeru.

N-umuyoboro MOSFETs ufite byinshi byiza biranga nka:

Kwinjira kwinshi:Irembo n'umuyoboro wa MOSFET bitandukanijwe nigice cyiziritse, bikavamo impedance yo hejuru cyane.

Urusaku ruke:Kubera ko imikorere ya MOSFETs itarimo gutera inshinge no guhuza abatwara bake, urusaku ni ruto.

Gukoresha ingufu nke: MOSFETs ikoresha ingufu nke haba muri leta no hanze.

Ibiranga umuvuduko mwinshi:MOSFETs ifite umuvuduko mwinshi wo guhinduranya kandi irakwiriye kumirongo yumurongo mwinshi hamwe numuvuduko mwinshi wa digitale.

IV. Ibice byo gusaba

N-umuyoboro MOSFETs ikoreshwa cyane mubikoresho bya elegitoroniki bitandukanye kubera imikorere myiza, nka:

Imirongo ya sisitemu:Nkibintu shingiro byinzira yumuzingi, ishyira mubikorwa gutunganya no kugenzura ibimenyetso bya digitale.

Inzira ya Analogue:Byakoreshejwe nkibintu byingenzi mubice bya analogue nka amplifier na filtri.

Amashanyarazi:Ikoreshwa mugucunga ibikoresho bya elegitoroniki nko guhinduranya amashanyarazi na moteri.

Ibindi bice:Nkurumuri rwa LED, ibikoresho bya elegitoroniki, itumanaho ridafite insinga nizindi nzego nazo zikoreshwa cyane.

Muri make, N-umuyoboro MOSFET, nkigikoresho cyingenzi cya semiconductor, igira uruhare rudasubirwaho mubuhanga bugezweho bwa elegitoroniki.
