N-Channel MOSFET, N-Channel Metal-Oxide-Semiconductor Field-Effect Transistor, wani muhimmin nau'in MOSFET ne. Mai zuwa shine cikakken bayani na MOSFETs N-channel:
I. Tsarin asali da abun da ke ciki
MOSFET ta tashar N-channel ta ƙunshi manyan abubuwa masu zuwa:
Kofa:tashar sarrafawa, ta hanyar canza wutar lantarki ta ƙofar don sarrafa tashar gudanarwa tsakanin tushen da magudanar ruwa.·
Source:Fitowa na yanzu, yawanci ana haɗa shi da mummunan gefen kewaye.·
Ruwa: shigowar halin yanzu, yawanci ana haɗawa da nauyin kewayawa.
Substrate:Yawancin nau'in P-type semiconductor abu, wanda aka yi amfani da shi azaman ma'auni don MOSFETs.
Insulator:Tana tsakanin ƙofar da tashar, yawanci ana yin ta da silicon dioxide (SiO2) kuma tana aiki azaman insulator.
II. Ka'idar aiki
Ka'idar aiki ta N-channel MOSFET ta dogara ne akan tasirin wutar lantarki, wanda ke gudana kamar haka:
Matsayin yankewa:Lokacin da wutar lantarki ta ƙofar (Vgs) ta yi ƙasa da ƙarfin ƙarfin kofa (Vt), ba a samar da tashar sarrafa nau'in N a cikin nau'in nau'in nau'in P da ke ƙasan ƙofar, don haka yanayin yankewa tsakanin tushen da magudanar ruwa yana cikin wurin. kuma halin yanzu ba zai iya gudana ba.
Yanayin aiki:Lokacin da ƙarfin ƙarfin ƙofar (Vgs) ya fi ƙarfin ƙarfin kofa (Vt), ramukan da ke cikin nau'in nau'in nau'in P da ke ƙasan ƙofar suna korarsu, suna samar da ƙarancin lalacewa. Tare da ƙarin haɓaka ƙarfin lantarki na ƙofar, electrons suna jan hankalin saman nau'in nau'in nau'in P, suna samar da tashar gudanarwa ta nau'in N. A wannan lokaci, an kafa hanya tsakanin tushen da magudanar ruwa kuma halin yanzu na iya gudana.
III. Nau'i da halaye
MOSFET na tashar N-tashar za a iya rarraba su zuwa nau'ikan nau'ikan daban-daban bisa ga halayensu, kamar Haɓaka-Yanayin da Yanayin Ragewa. Daga cikin su, MOSFETs na haɓaka-Yanayin suna cikin yanayin yankewa lokacin da wutar lantarki ta ƙofar ba ta cika ba, kuma tana buƙatar amfani da ingantaccen ƙarfin ƙofa don gudanarwa; yayin da MOSFETs-Yanayin Ragewa sun riga sun kasance a cikin yanayin gudanarwa lokacin da wutar lantarki ta ƙofar ba ta kasance ba.
MOSFETs N-channel suna da kyawawan halaye masu yawa kamar:
Babban shigarwar impedance:Ƙofar MOSFET da tashar MOSFET an keɓe su ta hanyar rufin rufi, wanda ke haifar da matsanancin shigarwar shigarwa.
Karancin amo:Tun da aikin MOSFETs ba ya haɗa da allura da haɗaɗɗun masu ɗaukar tsirarun, hayaniya ba ta da ƙarfi.
Ƙananan amfani da wutar lantarki: MOSFETs suna da ƙarancin amfani da wutar lantarki a duka jihohi da waje.
Halayen sauyawa mai sauri:MOSFETs suna da saurin sauyawa da sauri kuma sun dace da manyan da'irori masu girma da kuma da'irar dijital mai sauri.
IV. Yankunan aikace-aikace
MOSFETs N-channel ana amfani da su sosai a cikin na'urorin lantarki daban-daban saboda kyakkyawan aikinsu, kamar:
Da'irori na Dijital:A matsayin ainihin abin da'irori na ƙofar dabaru, yana aiwatar da sarrafawa da sarrafa siginar dijital.
Na'urorin Analogue:Ana amfani da shi azaman maɓalli a cikin da'irori na analog kamar amplifiers da masu tacewa.
Wutar Lantarki:An yi amfani da shi don sarrafa na'urorin lantarki masu amfani da wutar lantarki kamar sauya kayan wuta da tuƙi.
Sauran wurare:Irin su hasken LED, na'urorin lantarki na mota, sadarwa mara waya da sauran fagage kuma ana amfani da su sosai.
A taƙaice, N-channel MOSFET, a matsayin na'ura mai mahimmanci na semiconductor, yana taka rawar da ba za a iya maye gurbinsa ba a cikin fasahar lantarki ta zamani.
