Na u tseba lipalo tse tharo tsa MOSFET?

MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) e na le lipalo tse tharo tseo e leng:

Keiti:G, heke ya MOSFET e lekana le motheo wa bipolar transistor mme e sebediswa ho laola tsamaiso le ho kgaolwa ha MOSFET. Ho MOSFETs, motlakase oa liheke (Vgs) o etsa qeto ea hore na mocha oa conductive o thehoa pakeng tsa mohloli le metsi, hammoho le bophara le conductivity ea mocha oa conductive. Heke e entsoe ka lisebelisoa tse kang tšepe, polysilicon, joalo-joalo, 'me e pota-potiloe ke lesela la insulating (hangata silicon dioxide) ho thibela hona joale ho phalla ka ho toba kapa ho tsoa ka ntle ho heke.

Mohloli:S, mohloli oa MOSFET o lekana le emitter ea bipolar transistor mme ke moo hona joale e phallang teng. Ho li-MOSFET tsa N-channel, mohloli hangata o hokahantsoe le terminal e fosahetseng (kapa fatše) ea phepelo ea motlakase, ha ho P-channel MOSFETs, mohloli o hokahantsoe le terminal e ntle ea phepelo ea motlakase. Mohloli ke e 'ngoe ea likarolo tsa bohlokoa tse etsang mocha oa ho tsamaisa, o romelang li-electrone (N-channel) kapa masoba (P-channel) ho ea ho drain ha motlakase oa heke o phahame ka ho lekaneng.

Khala:D, drainage ea MOSFET e lekana le mokelli oa bipolar transistor 'me ke moo metsi a phallang teng. Mokelikeli o atisa ho hokahanngoa le mojaro 'me o sebetsa e le tlhahiso ea hona joale potolohong. Ho MOSFET, drainage ke karolo e 'ngoe ea mocha oa conductive,' me ha motlakase oa heke o laola ho thehoa ha mocha oa conductive pakeng tsa mohloli le drain, metsi a ka phalla ho tloha mohloling ka mocha oa conductive ho ea ho drain.

Ka bokhuts'oanyane, heke ea MOSFET e sebelisoa ho laola le ho tima, mohloli ke moo metsi a phallang teng, 'me drainage ke moo metsi a phallang teng. Ka kopanelo, lipalo tsena tse tharo li supa boemo ba ts'ebetso le ts'ebetso ea MOSFET. .
