Koho MOSFET | N-Channel MOSFET Nā Kuleana Hana

ʻO ka hana Metal-Oxide-SemIConductor o ka transistor aniani i ʻike mau ʻiaMOSFET, kahi i hoʻokaʻawale ʻia ai nā MOSFET i nā MOSFET ʻano P a me nā MOSFET ʻano N. ʻO nā kaʻapuni hoʻohui i haku ʻia me nā MOSFET, ua kapa ʻia hoʻi ʻo MOSFET integrated circuits, a ʻo nā moʻo pili pili pili MOSFET i haku ʻia me nā PMOSFET aNā NMOSFET ua kapa ʻia ʻo CMOSFET integrated circuits.

ʻO kahi MOSFET i loaʻa i kahi substrate ʻano-p a me ʻelua mau wahi pālahalaha n me nā koina koʻikoʻi kiʻekiʻe i kapa ʻia he n-channel.MOSFET, a o ke auwai conductive i hanaia e ke ano n-type conductive channel i hanaia e na ala hoolaha n ma na ala hoolaha n elua me na koina hookuonoono kiekie ke holo ka paipu. Loaʻa i nā MOSFET mānoanoa n-channel ka n-channel i hoʻokumu ʻia e kahi ala conductive i ka wā e hoʻokiʻekiʻe ʻia ai ka ʻaoʻao kūpono ma ka ʻīpuka a aia wale nō ke koi ʻia ka hana kumu o ka puka i kahi uila hana ma mua o ka volta paepae. ʻO nā MOSFET hoʻoemi n-channel ka mea i mākaukau ʻole i ka volta puka (pono ka hana kumu puka i ka volta hana o ka zero). ʻO ka MOSFET hoʻopau kukui n-channel he MOSFET n-channel kahi i hoʻokumu ʻia ai ke kahawai conductive inā ʻaʻole i mākaukau ka puka uila (ʻo ke kumu hana o ka ʻīpuka e koi ana i ka volta hana).

NMOSFET integrated circuits he N-channel MOSFET power supply circuit, NMOSFET integrated circuits, he kiʻekiʻe loa ka hoʻokomo ʻana, ʻaʻole pono ka hapa nui e ʻeli i ka absorption o ke kahe mana, a no laila ʻo CMOSFET a me NMOSFET hui pū ʻia me ka ʻole e lawe i loko. mooolelo i ka haawe o ka mana kahe.NMOSFET hui kaapuni, ka nui o ke koho ana o ka hookahi-hui pono hoololi mana lako kaapuni kaapuni mana lako kaapuni Ka hapanui o NMOSFET hoʻohana kaapuni hoʻohui i hoʻokahi hoʻololi mana hoʻolako mana kaapuni mana lako kaapuni, a i 9V no ka oi. Pono nā CMOSFET hui pū ʻia e hoʻohana i ka hoʻololi ʻana i ka mana lako kaapuni kaapuni e like me ka NMOSFET integrated circuits, hiki ke hoʻopili koke ʻia me NMOSFET integrated circuits. Eia naʻe, mai NMOSFET a CMOSFET pili koke, no ka mea, ʻoi aku ka liʻiliʻi o ke kū'ē huki huki ʻana o ka NMOSFET ma mua o ka CMOSFET integrated circuit kiʻi huki huki ʻana, no laila e hoʻāʻo e hoʻopili i kahi ʻokoʻa hiki ke huki-up resistor R, ka waiwai o ka resistor R maʻamau 2 i 100KΩ.

Ke kūkulu ʻana i nā MOSFET mānoanoa N-kanal
Ma ke ʻano P-type silicon substrate me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ua hana ʻia ʻelua mau ʻāpana N me ka waiwai hoʻopaʻa doping kiʻekiʻe, a huki ʻia ʻelua mau electrodes mai loko mai o ka metala alumini e lilo i kahawai d a me ke kumu s, kēlā me kēia.

A laila, i loko o ka semiconductor mea ili masking i ka loa lahilahi papa o ka silica insulating paipu, i loko o ka auwai - kumu insulating paipu ma waena o ka auwai a me ke kumu o kekahi alumini electrode, e like me ka puka g.

I loko o ka substrate e alakaʻi i kahi electrode B, nona kahi MOSFET mānoanoa N-channel. Hoʻopili pinepine ʻia ke kumu MOSFET a me ka substrate, ʻo ka hapa nui o ka paipu i loko o ka hale hana ua pili lōʻihi iā ia, ua hoʻopili ʻia kona ʻīpuka a me nā electrodes ʻē aʻe ma waena o ka pahu.
