Ngokuphambene ne-dual spinning crystal triode, kuvame ukuzwakala ukuthi ukwenzaI-MOSFETukuziphatha akusebenzisi ukugeleza kukagesi, kodwa kudinga kuphela i-voltage ye-GS ukuthi ibe phezulu kunevelu ethile. Kulula ukwenza lokhu, ikakhulukazi sidinga isilinganiso esithile.
Ngokwesakhiwo se-MOSFET, singathola ku-GS, GD, kuzoba khona amandla e-parasitic, futhi idrayivu ye-MOSFET, empeleni, iwukushaja nokukhipha amandla. Ukushaja kwama-capacitor sidinga kuphela okwamanje kwanele, ngoba i-capacitor ngesikhathi sokushaja ilingana ne-capacitor njenge-short-circuit, ngalesi sikhathi i-current instantaneous izoba ngaphezu kwenani lesimo esijwayelekile. Ngakho-ke, bese sikhetha noma siklame uhlelo lwesifunda se-MOSFET, into yokuqala okufanele uyiqaphele usayizi we-short-circuit yamanje inganikezwa.
Okwesibili, i-NMOS, esetshenziswa kabanzi ekushayeleni okuphezulu, kufanele ivumele i-voltage yesango idlule i-voltage yomthombo lapho iqhuba. I-MOSFET yedrayivu ephezulu ngesikhathi, amandla kagesi omthombo kanye nosayizi we-voltage wokudonsa kuyafana, ngakho kulokhu i-voltage yesango kufanele ibe yi-4V noma i-10V enkulu kune-Vcc. Uma ohlelweni olufanayo, ufuna ukuba mkhulu kune-voltage yesango le-Vcc, udinga uchwepheshe ekulawuleni isekethe ye-voltage. Abashayeli bezimoto abaningi bakhiwe ngamaphampu wokushaja, kufanele kuqashelwe ukuthi kufanele sikhethe i-capacitor yangaphandle efanele, ukuze sithole i-short-circuit current eyanele ukushayela i-MOSFET.
Ithimba elingu-Olueky core lisebenza ngokukhethekile ezingxenyeni ezithile, elinekomkhulu e-Shenzhen. Okuyinhloko:I-MOSFET, MCU, IGBT namanye amadivaysi. Imikhiqizo ye-ejenti eyinhlokoWINSOK, Cmsemicon. imikhiqizo isetshenziswa kakhulu kwezempi, ukulawula izimboni, amandla amasha, imikhiqizo yezokwelapha, i-5G, i-inthanethi Yezinto, ikhaya elihlakaniphile, kanye nobuchwepheshe obuhlukahlukene bomthengi. Kuncike ezinzuzweni zomenzeli ojwayelekile wangempela womhlaba, ngokusekelwe emakethe yaseShayina. Ukusebenzisa izinzuzo zesevisi ephelele kumakhasimende ukwethula zonke izinhlobo zezingxenye ze-elekthronikhi ezisezingeni eliphezulu, ukusiza abakhiqizi ukukhiqiza imikhiqizo yekhwalithi ephezulu futhi banikeze isevisi ephelele.
