I-N-Channel MOSFET, i-N-Channel Metal-Oxide-Semiconductor Field-Effect Transistor, iwuhlobo olubalulekile lwe-MOSFET. Okulandelayo yincazelo eningiliziwe yama-MOSFET wesiteshi se-N:
I. Isakhiwo esiyisisekelo kanye nokwakheka
I-N-channel MOSFET iqukethe izingxenye ezinkulu ezilandelayo:
Isango:i-terminal yokulawula, ngokushintsha i-voltage yesango ukuze ulawule umzila ohambayo phakathi komthombo nokukhipha amanzi.· ·
Umthombo:Ukuphuma kwamanje, ngokuvamile kuxhunywe ohlangothini olubi lwesekethe.· ·
Khipha amanzi: ukungena kwamanje, ngokuvamile okuxhunywe kumthwalo wesifunda.
I-Substrate:Ngokuvamile impahla yohlobo lwe-P-semiconductor, esetshenziswa njenge-substrate yama-MOSFET.
I-insulator:Itholakala phakathi kwesango nesiteshi, ngokuvamile yenziwe nge-silicon dioxide (SiO2) futhi isebenza njengesivikeli.
II. Isimiso sokusebenza
Isimiso sokusebenza se-N-channel MOSFET sisekelwe kumphumela wenkundla kagesi, oqhubeka kanje:
Isimo sokusika:Lapho i-voltage yesango (Vgs) ingaphansi kwe-threshold voltage (Vt), akukho siteshi esiqhuba uhlobo lwe-N esakhiwe ku-substrate yohlobo lwe-P ngaphansi kwesango, ngakho-ke isimo sokunqanyulwa phakathi komthombo nokukhipha amanzi sisendaweni. futhi okwamanje akukwazi ukugeleza.
Isimo sokuqhuba:Lapho i-voltage yesango (i-Vgs) iphakeme kune-voltage ye-threshold (Vt), izimbobo ku-substrate yohlobo lwe-P ngaphansi kwesango ziyaxoshwa, zenze isendlalelo sokunciphisa. Ngokukhula okwengeziwe kwe-voltage yesango, ama-electron akhangwa ebusweni be-substrate yohlobo lwe-P, enza isiteshi sokuqhuba uhlobo lwe-N. Kuleli qophelo, umzila uyakhiwa phakathi komthombo kanye ne-drain futhi i-current ingageleza.
III. Izinhlobo nezici
I-N-channel MOSFETs ingahlukaniswa ngezinhlobo ezahlukahlukene ngokuya ngezici zayo, njengeModi Yokuthuthukisa kanye Nemodi Yokuqeda. Phakathi kwawo, ama-MOSFET eNdlela Yokuthuthukisa asesimweni sokunqanyulwa lapho i-voltage yesango inguziro, futhi adinga ukusebenzisa i-voltage yesango elihle ukuze aqhube; kuyilapho ama-MOSFET e-Depletion-Mode asevele esesimweni sokuqhuba lapho i-voltage yesango inguziro.
I-N-channel MOSFET inezici eziningi ezinhle kakhulu ezifana nalezi:
I-impedance ephezulu yokufaka:Isango kanye neshaneli ye-MOSFET kuhlukaniswe ungqimba oluvikelayo, okuholela ekubambeni okuphezulu kakhulu kokufaka.
Umsindo ophansi:Njengoba ukusebenza kwama-MOSFET kungabandakanyi umjovo nokuhlanganiswa kwabathwali abambalwa, umsindo uphansi.
Ukusetshenziswa kwamandla okuphansi: Ama-MOSFET anokusetshenziswa kwamandla okuphansi kuzo zombili izifunda ezivuliwe noma ezivaliwe.
Izici zokushintsha ngesivinini esikhulu:Ama-MOSFET anesivinini sokushintsha esisheshayo futhi afanele amasekhethi emvamisa ephezulu kanye namasekhethi edijithali anesivinini esikhulu.
IV. Izindawo zokufaka isicelo
Ama-MOSFET we-N-channel asetshenziswa kakhulu kumishini kagesi ehlukahlukene ngenxa yokusebenza kwayo okuhle kakhulu, njenge:
Izifunda Zedijithali:Njengengxenye eyisisekelo yamasekhethi esango le-logic, isebenzisa ukucutshungulwa nokulawula amasignali edijithali.
Amasekhethi e-analogue:Isetshenziswa njengengxenye eyinhloko kumasekhethi e-analogue njengama-amplifiers nezihlungi.
Amandla kagesi:Isetshenziselwa ukulawula izinsiza zikagesi ezinjengokushintsha izinto zamandla kanye namadrayivu ezimoto.
Ezinye izindawo:Okufana nokukhanyisa kwe-LED, ugesi wezimoto, ukuxhumana okungenantambo nezinye izinkambu nazo zisetshenziswa kabanzi.
Kafushane, i-N-channel MOSFET, njengethuluzi elibalulekile le-semiconductor, idlala indima engenakuthathelwa indawo kubuchwepheshe besimanje be-elekthronikhi.
