Ukuqonda uLwakhiwo lweMOSFET yaMandla

Ii-MOSFET zamandla zizinto ezibalulekileyo kumbane wanamhlanje, eziyilelwe ukuphatha amandla ombane aphezulu kunye nemisinga. Makhe siphonononge iimpawu zabo zolwakhiwo ezizodwa ezenza amandla okuphatha amandla afanelekileyo.

Ulwakhiwo oluthe nkqo

Ngokungafaniyo nee-MOSFETs eziqhelekileyo, ii-MOSFETs zamandla zisebenzisa isakhiwo esithe nkqo apho ngoku kuqukuqela ukusuka phezulu (umthombo) ukuya ezantsi (drain), ukwandisa amandla okuphatha ngoku.

Ingingqi yeDrift

Iqulethe indawo encinci ye-n-doped exhasa amandla ombane aphezulu okuthintela kwaye ilawule ukuhanjiswa kombane.

Amacandelo angundoqo oLwakhiwo

Umthombo wesinyithi:Umaleko wesinyithi ophezulu wokuqokelela kunye nokuhanjiswa kwangoku
N+ Imimandla yoMthombo:Imimandla ene-doped kakhulu yokutofa komthwali
Ingingqi ye-p-Body:Yenza umjelo wokuqukuqela kwangoku
N- INgingqi yoDrift:Ixhasa amandla okuthintela amandla ombane
n+ Substrate:Ibonelela ngendlela ephantsi yokumelana nokukhupha amanzi
Drain Metal:Uqhagamshelwano olusezantsi lwentsimbi lokuhamba kwangoku
