Ngokuchaseneyo ne-crystal triode ejikeleza kabini, kuvakala ukuba ukwenza iI-MOSFETukuziphatha akusebenzisi ukuhamba kombane, kodwa kufuna kuphela umbane we-GS ukuba ube phezulu kunexabiso elithile. Kulula ukwenza oku, ikakhulu sidinga izinga elithile.
Kwisakhiwo se-MOSFET, sinokuyifumana kwi-GS, GD, kuya kubakho i-parasitic capacitance, kunye ne-MOSFET drive, enyanisweni, kukuhlawula kunye nokukhupha amandla. Ukutshaja kwee-capacitors sifuna kuphela i-current yanele ngokwaneleyo, kuba i-capacitor ngexesha lokuhlawula lilingana ne-capacitor njenge-short-circuit, ngeli xesha i-current current iya kuba phezulu kunexabiso lemeko jikelele. Ke ngoko, sikhetha okanye siyile inkqubo yesekethe ye-MOSFET, into yokuqala yokunikela ingqalelo kubungakanani bomjelo omfutshane wesekethe yangoku inokubonelelwa.
Okwesibini, i-NMOS, esetyenziswa ngokubanzi kwi-high end drive, kufuneka ivumele i-voltage yesango idlule umbane womthombo xa iqhuba. I-MOSFET ye-high-end drive ngexesha, umbane wemvelaphi kunye nobukhulu bombane wokudonsa kuyafana, ngoko ngeli xesha i-voltage yesango kufuneka ibe yi-4V okanye i-10V enkulu kune-Vcc. Ukuba ukwinkqubo efanayo, ufuna ukufumana amandla ombane wesango elikhulu le-Vcc, kufuneka uncuphe ekulawuleni isekethe yombane. Abaqhubi beemoto ezininzi benziwe ngeempompo zentlawulo, kufuneka kuqatshelwe ukuba kufuneka sikhethe i-capacitor yangaphandle efanelekileyo, ukuze sifumane i-short-circuit current eyaneleyo ukuqhuba i-MOSFET.
Olueky core iqela lisebenza ngokukhethekileyo kumacandelo, ikomkhulu e Shenzhen. Engundoqo:I-MOSFET, MCU, IGBT kunye nezinye izixhobo. Iimveliso zearhente eziphambiliWINSOK, Cmsemicon. iimveliso zisetyenziswa kakhulu emkhosini, kulawulo lwemizi-mveliso, amandla amatsha, iimveliso zonyango, i-5G, i-Intanethi yeZinto, ikhaya elilumkileyo, kunye nezinto ezahlukeneyo zombane zabathengi. Ukuxhomekeka kwiinzuzo ze-arhente yehlabathi jikelele yokuqala, ngokusekelwe kwimarike yaseTshayina. Ukusebenzisa iingenelo zenkonzo egqibeleleyo kubathengi ukwazisa zonke iintlobo zamacandelo obuchwepheshe obuphezulu be-elektroniki, ukunceda abavelisi ukuvelisa iimveliso ezikumgangatho ophezulu kunye nokubonelela ngenkonzo egqibeleleyo.
