Aqoonsiga Albaabka Lakabka Dahaaran ee MOSFETs

Iridka lakabka dahaarka nooca MOSFET aliasMOSFET (Hadda ka dib waxaa loo yaqaan MOSFET), kaas oo leh galka fiilada ee Silicon dioxide ee dhexda danabka albaabka iyo qulqulka isha.

MOSFET sidoo kale waaN-channel iyo P-channel laba qaybood, laakiin qayb kastaa waxa loo qaybiyaa kor u qaadida iyo nuurka nooca labaad, sidaas darteed waxaa jira wadar ahaan afar nooc:N-kanaalka kobcinta, Kor u qaadida kanaalka P-channel, N-kanaalka nalka oo yaraada, P-channel nooca nalka nalka. Laakiin meesha danab isha iridda waa eber, hadda biya shubay sidoo kale waa eber ee tuubada la wanaajiyey. Si kastaba ha ahaatee, halka korantada isha irridda ay eber tahay, qulqulka qulqulaya ma aha eber waxaa loo kala saaraa sida tubooyinka nooca iftiinka cunaya.
Mabda'a MOSFET ee la xoojiyey:

Marka ka shaqeeya dhexe ee isha iridda ma isticmaalaan danab, dhexe ee isha godka PN isgoysyada waa jihada ka soo horjeeda, sidaas darteed ma jiri doono channel conductive, xitaa haddii dhexe ee isha dheecaan la danab ah, the Korontada jeex-jeexa waa xiran tahay, suurtagal maaha in la haysto hadda shaqeeya sida waafaqsan. Marka dhexe ee isha iridda oo lagu daray danab jihada togan in qiimo gaar ah, in dhexe ee isha dheecaan soo saari doonaa kanaalka badbaadada conductive, si ay godka conductive kaliya soo saaray by danab il this albaabka waxaa loo yaqaan danab furan VGS, dhexda weyn ee danab isha iridda, godka conductive waa ka sii ballaaran, taas oo iyana ka dhigaysa dhex socodka weyn ee korontada.

Mabaadi'da Iftiinka Kala-baxa MOSFET:

Hawlgalka, wax danab ah looma isticmaalo bartamaha isha albaabka, si ka duwan nooca xoojinta MOSFET, iyo kanaalka korantada ayaa ka jira bartamaha isha qulqulka, sidaas darteed kaliya koronto togan ayaa lagu daraa bartamaha isha qulqulka, kaas oo waxay keentaa qulqulka qulqulka hadda socda. Waxaa intaa dheer, isha iridda ee dhexe ee jihada togan ee danab, ballaarinta channel conductive, ku dar jihada ka soo horjeeda ee danab, channel conductive yaraaday, iyada oo socodka korantada noqon doonaa yar yar, la kobcinta ee isbarbardhigga MOSFET. Waxa kale oo ay noqon kartaa tirada togan iyo kuwa taban ee tiro go'an oo gobollo ah oo ku dhex jira kanaalka korantada.

Waxtarka MOSFET:

Marka hore, MOSFET-yada waxaa loo isticmaalaa in lagu ballaariyo. Sababtoo ah iska caabin gelinta MOSFET amplifier aad buu u sarreeyaa, sidaas darteed korantada filtarku way yarayn kartaa, iyada oo aan loo baahnayn in la isticmaalo capacitors electrolytic.

Marka labaad, MOSFET iska caabin gelinta aad u sarreeya ayaa si gaar ah ugu habboon beddelidda cilladda sifada. Caadi ahaan loo isticmaalo marxaladda gelista cod-weyneeye heer-badan ah si loo beddelo impedance.

MOSFET waxa loo isticmaali karaa sidii resistor la hagaajin karo.

Afar, MOSFET waxay noqon kartaa mid ku habboon sahayda korantada DC ahaan.

V. MOSFET waxa loo isticmaali karaa sidii curiye beddelaad ah.
