Gane Ƙofar Layer da aka keɓe MOSFETs

Nau'in Ƙofar Insulation Layer MOSFET aliasMOSFET (nan gaba ana kiranta MOSFET), wanda ke da kullin kebul na silicon dioxide a tsakiyar wutar lantarki da magudanar ruwa.

MOSFET kumaN-channel da P-channel kashi biyu, amma kowane nau'i ya kasu kashi biyu na haɓakawa da ƙarancin haske, don haka akwai jimillar nau'i hudu:N-tashar haɓakawa, P-tashar haɓakawa, N-tashar haske mai lalacewa, nau'in raƙuman haske na P-tashar. Amma inda kofa tushen ƙarfin lantarki ne sifili, da lambatu halin yanzu kuma sifili na bututu suna inganta tube. Koyaya, inda ƙarfin tushen ƙofar ƙofar ya zama sifili, magudanar ruwa ba sifili ba ana kasafta su azaman bututu masu cin haske.
Ingantacciyar ƙa'idar MOSFET:

Lokacin da aiki a tsakiyar ƙofar tushen ba ya amfani da wutar lantarki, tsakiyar magudanar ruwa PN junction ne a cikin m shugabanci, don haka ba za a yi conductive tashar, ko da tsakiyar magudanar tushen da wani irin ƙarfin lantarki, da An rufe wutar lantarki na mahara, ba zai yiwu a sami halin yanzu mai aiki bisa ga ba. Lokacin da tsakiyar ƙofar tushen da tabbataccen shugabanci irin ƙarfin lantarki zuwa wani ƙima, a tsakiyar magudanar ruwa zai samar da conductive aminci tashar, sabõda haka, conductive mahara da kawai samar da wannan ƙofar tushen ƙarfin lantarki ne ake kira bude irin ƙarfin lantarki VGS, da ya fi girma tsakiyar wutar lantarki na tushen ƙofar, maɓalli mai ɗaukar nauyi ya fi fadi, wanda hakan ke haifar da mafi yawan kwararar wutar lantarki.

Ƙa'idar Hasken Rarraba MOSFET:

A cikin aiki, ba a yi amfani da wutar lantarki a tsakiyar ƙofar kofa ba, sabanin nau'in haɓakawa na MOSFET, kuma tashar sarrafawa tana wanzu a tsakiyar magudanar ruwa, don haka kawai ana ƙara ingantaccen ƙarfin lantarki zuwa tsakiyar magudanar ruwa, wanda ke haifar da haɓakar wutar lantarki. yana haifar da magudanar ruwa a halin yanzu. Haka kuma, tushen kofa a tsakiyar madaidaiciyar shugabanci na ƙarfin lantarki, haɓakar tashar watsawa, ƙara kishiyar wutar lantarki, tashar tashar tashar ta ragu, ta hanyar kwararar wutar lantarki za ta zama ƙarami, tare da haɓaka kwatancen MOSFET. Hakanan zai iya kasancewa a cikin tabbataccen lamba da mara kyau na takamaiman adadin yankuna a cikin tashar gudanarwa.

Tasirin MOSFET:

Na farko, ana amfani da MOSFET don ƙara girma. Saboda juriyar shigar da amplifier MOSFET yana da girma sosai, don haka capacitor na tacewa zai iya zama ƙarami, ba tare da buƙatar amfani da capacitors na electrolytic ba.

Na biyu, MOSFET babban juriya na shigarwa yana da dacewa musamman don jujjuyawar haɓakawa. Yawanci ana amfani da shi a matakin shigar da amplifier na matakai masu yawa don jujjuyawar siffa.

Ana iya amfani da MOSFET azaman resistor mai daidaitacce.

Na hudu, MOSFET na iya zama dacewa azaman wutar lantarki ta DC.

V. MOSFET za a iya amfani da shi azaman abin canzawa.
