Ukuqonda Amandla MOSFET Isakhiwo

Ama-MOSFET Amandla ayizingxenye ezibalulekile kugesi wamandla wesimanje, aklanyelwe ukuphatha ama-voltage aphezulu namaza. Ake sihlole izici zabo ezihlukile zesakhiwo ezivumela amandla okuphatha amandla asebenzayo.

Isakhiwo Esimile

Ngokungafani nama-MOSFET avamile, ama-MOSFET amandla asebenzisa isakhiwo esime mpo lapho kugeleza khona manje ukusuka phezulu (umthombo) kuye phansi (ukukhipha amanzi), okwandisa amandla okuphatha amanje.

Isifunda se-Drift

Iqukethe i-n- region ene-doped kancane esekela amandla kagesi avinjiwe futhi elawula ukusatshalaliswa kwenkundla kagesi.

Izingxenye Ezibalulekile Zesakhiwo

Umthombo Wensimbi:Isendlalelo sensimbi esiphezulu sokuqoqwa nokusabalalisa kwamanje
Izifunda zomthombo we-n+:Izifunda ezine-doped kakhulu zomjovo wenkampani yenethiwekhi
p-Body Region:Idala isiteshi sokugeleza kwamanje
Isifunda se-n-Drift:Isekela amandla okuvimbela i-voltage
I-n+ Substrate:Inikeza indlela yokumelana ephansi yokukhipha amanzi
I-Drain Metal:Ukuthintana kwensimbi engezansi kokugeleza kwamanje
