I-N-Channel MOSFET, i-N-Channel Metal-Oxide-Semiconductor Field-Effect Transistor, luhlobo olubalulekileyo lwe-MOSFET. Oku kulandelayo yingcaciso ebanzi yee-N-channel MOSFETs:
I. Ubume obusisiseko kunye nokwakheka
I-N-channel MOSFET inala macandelo alandelayo:
Isango:i-terminal yokulawula, ngokutshintsha i-voltage yesango ukulawula i-channel conductive phakathi komthombo kunye ne-drain.· ·
Umthombo:Ukuphuma kwangoku, ngokuqhelekileyo kuxhunywe kwicala elibi lesekethe.· ·
Khupha amanzi: ukungena kwangoku, ngokuqhelekileyo kuxhunywe kumthwalo wesiphaluka.
Inkqutyana:Ngokuqhelekileyo i-P-type semiconductor imathiriyeli, esetyenziswa njenge-substrate yee-MOSFETs.
Isigqubuthelo:Ifumaneka phakathi kwesango kunye neshaneli, ngokuqhelekileyo yenziwe nge-silicon dioxide (SiO2) kwaye isebenza njenge-insulator.
II. Umgaqo wokusebenza
Umgaqo wokusebenza we-N-channel MOSFET usekwe kwisiphumo sebala lombane, oqhubeka ngolu hlobo lulandelayo:
Imo yokusikwa:Xa i-voltage yesango (i-Vgs) iphantsi kune-voltage ye-threshold (Vt), akukho mjelo wokuqhuba uhlobo lwe-N lwenziwa kwi-substrate yohlobo lwe-P ngaphantsi kwesango, kwaye ngoko ke imeko yokunqunyulwa phakathi komthombo kunye ne-drain ikhona. kwaye umsinga awukwazi ukuhamba.
Imeko yokuqhuba:Xa i-voltage yesango (i-Vgs) iphezulu kune-voltage ye-threshold (Vt), izimbobo kwi-substrate yohlobo lwe-P ngaphantsi kwesango iyagxothwa, yenze i-depletion layer. Ngokunyuka ngakumbi kwi-voltage yesango, ii-electron zitsalwa kumphezulu we-P-type substrate, zenza i-N-type conducting channel. Ngeli xesha, indlela yenziwa phakathi komthombo kunye ne-drain kunye ne-current can flow.
III. Iintlobo kunye neempawu
I-N-channel MOSFETs inokuhlelwa kwiindidi ezahlukeneyo ngokweempawu zazo, ezifana neModi yoPhuculo kunye neModi yokunciphisa. Phakathi kwazo, ii-MOSFETs zeNdlela yoPhuculo zikwimeko yokunqunyulwa xa isango lombane liyi-zero, kwaye kufuneka lifake umbane wesango eliqinisekileyo ukuze liqhube; ngelixa i-Depletion-Mode MOSFETs sele ikwimo yokuqhuba xa i-voltage yesango ingu-zero.
I-N-channel MOSFET ineempawu ezininzi ezintle ezifana nezi:
I-impedance ephezulu:Isango kunye nejelo le-MOSFET libekwe lodwa ngumaleko wokugquma, okhokelela kuthintelo oluphezulu kakhulu.
Ingxolo ephantsi:Kuba ukusebenza kwee-MOSFET kungabandakanyi inaliti kunye nokudibanisa abathwali abambalwa, ingxolo iphantsi.
Ukusetyenziswa kwamandla aphantsi: Ii-MOSFETs zinosetyenziso oluphantsi lwamandla kuzo zombini iindawo ezingaphakathi nangaphandle.
Iimpawu zokutshintsha kwesantya esiphezulu:Ii-MOSFETs zinezantya zokutshintsha ezikhawulezayo kwaye zifanelekile kwiisekethe ezihamba rhoqo kunye neesekethe zedijithali ezinesantya esiphezulu.
IV. Iindawo zesicelo
Ii-MOSFET ze-N-channel zisetyenziswa ngokubanzi kwizixhobo zombane ezahlukeneyo ngenxa yokusebenza kwazo okugqwesileyo, ezinje:
IiSekethe zeDijithali:Njengento esisiseko yeesekethe zesango le-logic, izalisekisa ukusetyenzwa kunye nokulawulwa kweempawu zedijithali.
Iisekethe ze-analogue:Isetyenziswe njengecandelo eliphambili kwiisekethe ze-analogue ezifana ne-amplifiers kunye nezihlungi.
Umbane woMbane:Isetyenziselwa ukulawula izixhobo zombane zombane ezifana nokutshintsha izixhobo zombane kunye neemoto zokuqhuba.
Ezinye iindawo:Okufana nezibane ze-LED, ii-elektroniki zeemoto, unxibelelwano lwamacingo kunye nezinye iindawo nazo zisetyenziswa ngokubanzi.
Ngamafutshane, i-N-channel MOSFET, njengesixhobo esibalulekileyo se-semiconductor, idlala indima engenakuthatyathelwa indawo kubuchwephesha be-elektroniki bale mihla.
