Makhalidwe a MOSFET

MOSFET conductivity imatanthawuza kuti imagwiritsidwa ntchito ngati chosinthira, chomwe chiri chofanana ndi kusintha kotsekera.NMOS imadziwika kuti ikuyendetsa pamene Vgs idutsa mtengo wochepa, womwe umakhudzana ndi chikhalidwe ndi gwero lolumikizidwa ndi chipangizo chokhazikika, ndipo chimangofunika chipata. voteji kukhala 4V kapena 10V.PMOS, kumbali ina, imachita pamene Vgs ikugwera pansi pa mtengo wina, ndipo ndi yoyenera pazochitika zomwe gwero likugwirizana ndi Vcc. Komabe, ngakhale PMOS ikhoza kukhala yabwino ngati dalaivala wapamwamba kwambiri, NMOS imagwiritsidwa ntchito poyendetsa madalaivala apamwamba chifukwa cha kukana kwakukulu, kukwera mtengo ndi mtengo, ndi mitundu yochepa yosinthira.

Kaya izo ziriNMOSkapena PMOS, padzakhala kutsutsa pambuyo pa kukana, kotero kuti panopa mu kukana kudya kuchuluka kwa mphamvu, kumwa uku kumatchedwa kutayika kwa kukana. Pakadali pano, timangosankha kukana kwa MOSFET yaying'ono kumatha kuchepetsa kutayika kwa kukana, kutsika kwamasiku ano.MOSFETon-resistance nthawi zambiri amakhala mamiliyoni ambiri, kapena ma miliohm ochepa chabe a mawonekedwe a MOS potengera kukwaniritsidwa kwa zinthu sizichitika mwachangu.
Mphamvu yamagetsi kumbali zonse ziwiri za MOS ili ndi njira yochepetsera, yomwe ikuyenda pakalipano ikuwonjezeka, panthawiyi, mphamvu yamagetsi ndi yamakono ikuchulukitsidwa ndi kukula kwa kutayika kwa MOSFET. Kusintha kwanthawi zonse kumakhala kokulirapo kuposa kutayika kwa conduction, ndipo ngati kusinthasintha kwanthawi yayitali, kutayika kwakukulu. Kuchulukirachulukira kwa voteji ndi komwe kukuchitika panthawi ya conduction, kumapangitsanso kutaya kwakukulu. Ngati titha kuchepetsa nthawi yosinthira, titha kuchepetsa kutayika pamayendedwe aliwonse, kuchepetsa kusinthasintha kwanthawi zonse, komanso kuchepetsa kusinthasintha kwanthawi yayitali, kuti muchepetse kutayika kosinthika.

Kupyolera mu chitukuko chamsika chogwira ntchito komanso kuphatikiza kwazinthu zogwira mtima, olukey wakhala m'modzi mwa otsogola komanso omwe akukula mwachangu ku Asia, ndipo ndi cholinga chodziwika bwino cha olukey kukhala wothandizira wofunika kwambiri padziko lonse lapansi. Kwa zaka zambiri, kampani olukey kupulumuka ngongole, kutsatira "khalidwe loyamba, utumiki choyamba" cholinga ndi mabizinezi ambiri zoweta ndi akunja apamwamba chatekinoloje, fakitale choyambirira kukhazikitsa ubale wabwino ntchito, ndi zaka zambiri akatswiri zinachitikira kugawa, ndi ngongole yabwino, ntchito yabwino kwambiri, komanso kupeza chidaliro ndi chithandizo chambiri.
