MOSFET: isenzo kanye kwenkululeko isimiso

Ukutadisha izakhiwo elinama ezifana Semiconductor, akavunyelwe ukwenza okutholakele wamavukelambuso. Ngokuhamba kwesikhathi lapho ubuchwepheshe ngokuhweba ukukhiqiza diodes, Mos transistors, thyristors nezinye izakhi. Bona ngempumelelo esikhundleni cleaner amashubhu futhi bavunyelwe ukuba uqaphele imibono kwakwakhiwa kakhulu. izingxenye semiconductor asetshenziswa yonke imikhakha yempilo yethu. Basenza ukucubungula oluningi kakhulu ulwazi ngesisekelo amakhompyutha abo ekhiqizwa, itheyiphu abalobi, amathelevishini, njll

Kusukela kokusungulwa Transistor lokuqala, futhi kwaba ngo-1948, sekudlule isikhathi eside. Kwakuhlukahluka kwalesi sakhi: iphuzu germanium, i-silicon ensimini-nomphumela noma ama MOSFET. Bonke kabanzi zikagesi. Ucwaningo we izakhiwo Semiconductors ngeke ayeke esikhathini sethu.

Lezi izifundo ziye zaholela ukuvela idivayisi ezifana MOSFET. Umgomo we operation kusekelwe yokuthi emkhakheni kagesi (kungakho elinye igama - ensimini) kuyahlukahluka le conductivity ka kobuso ungqimba Semiconductor emkhawulweni ne Kwe-dielectric Heating. Le mpahla isetshenziswa izifunda ngogesi ngezinjongo ahlukahlukene. Mos Transistor has a isakhiwo okuvumela ukwehlisa ukumelana phakathi abakhwabanisi futhi umthombo ngaphansi kwethonya isignali ukulawula kakhulu zero.

Amandla ayo zihlukile yokuguquguquka "esincintisana". Is they yokubona ukwenaba komusa uhlelo lwayo lokusebenza.

• ukusebenza High ibangelwa miniaturizing crystal uqobo kanye izakhiwo zayo eziyingqayizivele. Lokhu kungenxa nobunzima kwezinga lemikhiqizo yezimboni. Okwamanje, zinhlayiya akhiqizwa nge esangweni 0,06 Micron.
• A shintsho capacitance ezincane kwenza lezi amadivaysi usebenze okusezingeni eliphezulu imvamisa izifunda. Ngokwesibonelo, i-LSI nokusetshenziswa kwawo iye yasetshenziswa ukuxhumana mobile ngempumelelo.
• Cishe zero ukumelana, okuyinto has a MOSFET esimweni evulekile, ingasetshenziswa njengoba okhiye electronic. Abakwazi ukusebenza ezifundeni odala amasignali okusezingeni eliphezulu imvamisa noma ekuvaleni izici eziningana ezinjengolwazi yokukhulisa umsindo tekusebenta.
• amadivaysi Inamandla yalolu hlobo ziye zasetshenziswa ngempumelelo emandleni amamojuli futhi kungafakwa circuit lokungeniswa. Isibonelo esihle ngokusebenzisa kwawo kungase kube i-inverter.

Uma kuhlelelwa nokusebenza lezi zinto kubalulekile ukucabangela ezinye izici. MOSFETs nozwelo overvoltage futhi ukuhlanekezela kalula behluleka ukuphi. Izifunda inductance evame ukusetshenziswa ngesivinini Schottky diodes ngoba bushelelezi reverse voltage ishayela, okuyinto eyenzeka ngesikhathi ukushintsha.

Amathemba ukusetshenziswa kwalezi amadivayisi mikhulu. Ukuthuthukisa ubuchwepheshe ukwakhiwa kwazo izindlela zokunciphisa crystal (yesivalo uyakekela). Kancane kancane abasafufusa kumadivayisi bakwazi ukuphatha izinjini ezinamandla kakhudlwana.
