Matsayin MOSFETs a cikin da'irori

MOSFETstaka rawaa cikin sauyawa da'irorishine sarrafa kewayawa a kunne da kashewa da juyar da sigina.MOSFETs Za a iya raba shi zuwa kashi biyu: N-channel da P-channel.

A cikin N-channelMOSFETkewaye, Fitin BEEP yana da girma don ba da damar amsawar buzzer, kuma ƙananan don kashe buzzer.P-channelMOSFETdon sarrafa wutar lantarki na module GPS a kunne da kashewa, GPS_PWR fil yana da ƙasa idan kun kunna, GPS module ne wutar lantarki ta al'ada, kuma mai girma don sa ƙirar GPS ta kashe wuta.

P-tasharMOSFETa cikin nau'in siliki na nau'in N-type akan yankin P + yana da biyu: magudanar ruwa da tushe. Wadannan sandunan guda biyu ba su da motsi ga junansu, lokacin da aka sami isasshen wutar lantarki mai inganci da aka kara wa tushen lokacin da aka kasa kasa, shimfidar siliki mai nau'in N-type da ke ƙasan ƙofar zai fito a matsayin nau'in P-inverse Layer, zuwa tashar da ke haɗa magudanar ruwa da tushe. . Canza wutar lantarki a ƙofar yana canza girman ramuka a cikin tashar, don haka canza juriya na tashar. Wannan shi ake kira da transistor na inganta tasirin filin P-channel.

Halayen NMOS, Vgs idan dai mafi girma fiye da takamaiman ƙima za su kasance a kunne, masu amfani da tushen tushen ƙaramar tuƙi mai ƙarancin ƙarewa, muddin ƙarfin ƙarfin ƙofa na 4V ko 10V akan layin.

Halayen PMOS, sabanin NMOS, za su kunna muddin Vgs bai kai wani ƙima ba, kuma ya dace don amfani a yanayin babban tuƙi lokacin da aka haɗa tushen zuwa VCC. Koyaya, saboda ƙananan nau'ikan maye gurbin, tsayin juriya da farashi mai girma, kodayake ana iya amfani da PMOS sosai a cikin yanayin babban tuƙi, don haka a cikin babban tuƙi, gabaɗaya har yanzu suna amfani da NMOS.

Gabaɗaya,MOSFETssuna da babban abin shigar da bayanai, suna sauƙaƙe haɗa kai tsaye a cikin da'irori, kuma suna da sauƙin ƙirƙira cikin manyan da'irori masu haɗaka.
