Hariho itandukaniro ryinshi ryibimenyetso byumuzingi bikunze gukoreshwa kuri MOSFETS. Igishushanyo gikunze kugaragara ni umurongo ugororotse ugereranya umuyoboro, imirongo ibiri itondekanye kumuyoboro ugereranya inkomoko n'amazi, n'umurongo mugufi ugereranije numuyoboro ibumoso ugereranya irembo. Rimwe na rimwe, umurongo ugororotse uhagarariye umuyoboro nawo usimburwa n'umurongo wacitse kugirango utandukanye uburyo bwo kuzamuraumubu cyangwa depletion mode mosfet, nayo igabanijwemo N-umuyoboro MOSFET na P-umuyoboro MOSFET ubwoko bubiri bwibimenyetso byumuzingi nkuko bigaragara mumashusho (icyerekezo cyumwambi kiratandukanye).
Imbaraga MOSFETs ikora muburyo bubiri:
. na S. Niba hiyongereyeho voltage nziza UGS hagati ya G na S, ntamuyoboro wamarembo uzatemba kuko irembo ryakinguwe, ariko voltage nziza kumuryango izasunika umwobo kure yakarere ka P munsi, na electron zitwara abantu bake bazabikora gukururwa nubuso bwa P Mugihe UGS irenze voltage runaka UT, kwibanda kuri electron hejuru yakarere ka P munsi y irembo bizarenga umwobo, bityo bigatuma P-semiconductor antipattern layer N-semiconductor ; iyi antipattern igize umuyoboro wa N-hagati yinkomoko nisoko, kugirango ihuriro rya PN ribeho, isoko nisoko ryamazi, hamwe nindangamuntu yumuyoboro unyura mumazi. UT yitwa voltage-voltage cyangwa voltage yumubyigano, kandi uko UGS irenze UT, nubushobozi bwo kuyobora ni, kandi nini ID nini. Ninshi UGS irenze UT, imbaraga zikomeye, nindangamuntu nini.
.BYINSHI ntabwo ifite ubushobozi bwo guhagarika ubushobozi, irashobora gufatwa nkibice bitwara ibintu.
NaBYINSHI ihame ryimikorere rirashobora kugaragara, itwarwa ryayo gusa itwara polarite imwe gusa igira uruhare mugutwara, bityo ikaba izwi kandi nka unipolar transistor. Drive ya MOSFET akenshi iba ishingiye kumashanyarazi IC hamwe na MOSFET ibipimo byo guhitamo umuzenguruko ukwiye, MOSFET isanzwe ikoreshwa muguhindura amashanyarazi yo gutanga amashanyarazi. Mugihe utegura amashanyarazi ahinduranya ukoresheje MOSFET, abantu benshi batekereza kuri on-resistance, voltage nini, hamwe numuyoboro mwinshi wa MOSFET. Nyamara, abantu bakunze gutekereza gusa kubintu, kugirango uruziga rushobore gukora neza, ariko ntabwo ari igisubizo cyiza cyo gushushanya. Kubishushanyo mbonera birambuye, MOSFET nayo igomba gusuzuma amakuru yayo bwite. Kuri MOSFET isobanutse neza, umuzenguruko wacyo wo gutwara, impinga yumusaruro wibisohoka, nibindi, bizagira ingaruka kumikorere ya MOSFET.
