Momwe Mungadziwire ma nMOSFET ndi ma pMOSFET

I. Molingana ndi momwe akuyendetsedwera pano

NMOSFET:Pamene panopa ikuyenda kuchokera ku gwero (S) mpaka kukhetsa (D), MOSFET ndi NMOSFET Mu NMOSFET, gwero ndi kukhetsa ndi ma semiconductors amtundu wa n ndipo chipata ndi p-type semiconductor. Pamene magetsi a pachipata ali abwino pokhudzana ndi gwero, njira yoyendetsera mtundu wa n imapangidwa pamwamba pa semiconductor, kulola kuti ma electron ayende kuchokera ku gwero kupita kukhetsa.

PMOSFET:MOSFET ndi PMOSFET pamene panopa ikuyenda kuchokera ku drain (D) kupita ku gwero (S) Mu PMOSFET, gwero ndi kukhetsa ndi ma semiconductor amtundu wa p ndipo chipata ndi semiconductor yamtundu wa n. Pamene magetsi a pachipata ali oipa ponena za gwero, njira yoyendetsera mtundu wa p imapangidwa pamwamba pa semiconductor, yomwe imalola mabowo kutuluka kuchokera ku gwero kupita kukhetsa (zindikirani kuti m'mafotokozedwe ochiritsira timanenabe kuti panopa imachokera ku D kupita ku S, koma kwenikweni ndi njira yomwe mabowo amasunthira).

II. Malinga ndi parasitic diode malangizo

NMOSFET:Pamene parasitic diode ikuloza kuchokera ku gwero (S) kukhetsa (D), ndi NMOSFET. parasitic diode ndi mawonekedwe amkati mwa MOSFET, ndipo malangizo ake angatithandize kudziwa mtundu wa MOSFET.

PMOSFET:The parasitic diode ndi PMOSFET ikaloza kuchokera ku drain (D) kupita kugwero (S).

III. Malinga ndi ubale pakati pa kuwongolera ma elekitirodi voteji ndi madutsidwe magetsi

NMOSFET:NMOSFET imayendetsa pamene magetsi a geti ali abwino pokhudzana ndi gwero lamagetsi. Izi ndichifukwa choti magetsi olowera pachipata amapangitsa kuti ma semiconductor amtundu wa n-mtundu azitha kuyendetsa ma electron.

PMOSFET:PMOSFET imayendetsa pamene magetsi a pachipata ali oipa ponena za magetsi. Mpweya woipa wa chipata umapanga njira yoyendetsera mtundu wa p pamtunda wa semiconductor, kulola mabowo kuyenda (kapena akuyenda kuchokera ku D kupita ku S).

IV. Njira zina zothandizira chiweruzo

Onani zolembera pazida:Pa ma MOSFET ena, pakhoza kukhala chizindikiro kapena nambala yachitsanzo yomwe imadziwikitsa mtundu wake, ndipo poyang'ana tsatanetsatane wofunikira, mutha kutsimikizira ngati ndi NMOSFET kapena PMOSFET.

Kugwiritsa ntchito zida zoyesera:Kuyeza kukana kwa pini kwa MOSFET kapena kayendesedwe kake pamagetsi osiyanasiyana kudzera pa zida zoyesera monga ma multimeter kungathandizenso kudziwa mtundu wake.

Mwachidule, kuweruza kwa ma NMOSFET ndi ma PMOSFET kumatha kuchitidwa makamaka kudzera mumayendedwe omwe akuyenda pano, njira ya parasitic diode, ubale wapakati pamagetsi owongolera ma elekitirodi ndi ma conductivity, komanso kuyang'ana chizindikiro cha chipangizocho komanso kugwiritsa ntchito zida zoyesera. Muzogwiritsira ntchito, njira yoyenera yoweruza ingasankhidwe molingana ndi momwe zinthu zilili.
