Kuzindikira kwa Insulated Layer Gate MOSFETs

Insulation layer gate mtundu MOSFET aliasMOSFET (yotchedwa MOSFET), yomwe ili ndi chingwe cha silicon dioxide pakati pa magetsi a chipata ndi kukhetsa kwagwero.

MOSFET nayensoN-channel ndi P-channel magawo awiri, koma gulu lirilonse lagawidwa mu mtundu wachiwiri wowonjezera komanso kuchepa kwa kuwala, motero pali mitundu inayi:Kupititsa patsogolo njira ya N, Kuwongoleredwa kwa P-channel, kuchepa kwa kuwala kwa njira ya N, mtundu wa P-channel depletion light. Koma pamene chipata gwero voteji ndi ziro, kukhetsa panopa ndi ziro wa chitoliro ndi kumatheka chubu. Komabe, pomwe magetsi olowera pachipata ndi zero, madzi akukhetsa si ziro amagawidwa ngati machubu amtundu wogwiritsa ntchito kuwala.
Mfundo yowonjezera ya MOSFET:

Pamene ntchito pakati pa chipata gwero si ntchito voteji, pakati pa kuda gwero PN mphambano ali mbali ina, kotero sipadzakhala conductive njira, ngakhale pakati pa kuda gwero ndi voteji, ndi conductive ngalande magetsi chatsekedwa, sizingatheke kukhala ndi ntchito panopa malinga. Pamene pakati pa chipata gwero kuphatikiza zabwino malangizo voteji kwa mtengo wina, pakati pa kuda gwero adzatulutsa conductive chitetezo njira, kotero kuti ngalande conductive basi opangidwa ndi chipata gwero voteji amatchedwa lotseguka voteji VGS. chokulirapo pakati pa chipata gwero voteji, ngalande conductive ndi okulirapo, amenenso amapanga kudzera kwambiri otaya magetsi.

Mfundo ya Light Dissipative MOSFET:

Pogwira ntchito, palibe magetsi omwe amagwiritsidwa ntchito pakati pa gwero la chipata, mosiyana ndi mtundu wowonjezera wa MOSFET, ndipo njira yoyendetsera imakhalapo pakati pa gwero la kukhetsa, kotero kuti voteji yabwino yokha imawonjezedwa pakati pa gwero la kukhetsa. zimabweretsa kukhetsa kwa madzi. Komanso, gwero lachipata pakati pa njira yabwino ya voteji, kukulitsa njira yoyendetsera magetsi, kuwonjezera mbali ina yamagetsi, njira yoyendetsera magetsi imachepa, kupyolera mukuyenda kwa magetsi kudzakhala kochepa, ndi kupititsa patsogolo kufananitsa kwa MOSFET, ikhozanso kukhala mu chiwerengero chabwino ndi choipa cha chiwerengero cha zigawo mkati mwa njira yoyendetsera.

Kuchita bwino kwa MOSFET:

Choyamba, ma MOSFET amagwiritsidwa ntchito kukulitsa. Chifukwa kukana kolowera kwa MOSFET amplifier ndikokwera kwambiri, kotero capacitor yosefera imatha kukhala yaying'ono, popanda kufunika koyika ma electrolytic capacitors.

Chachiwiri, kukana kwambiri kwa MOSFET ndikoyenera kwambiri kutembenuka kwa chikhalidwe cha impedance. Nthawi zambiri amagwiritsidwa ntchito mumayendedwe amplifier amitundu ingapo kuti asinthe mawonekedwe a impedance.

MOSFET itha kugwiritsidwa ntchito ngati chopinga chosinthika.

Chachinayi, MOSFET ikhoza kukhala yabwino ngati magetsi a DC.

V. MOSFET itha kugwiritsidwa ntchito ngati chinthu chosinthira.
