MOSFET, inozivikanwa seMetal-Oxide-Semiconductor Field-Effect Transistor, inoshandiswa nemagetsi inoshandiswa zvakanyanya iyo ndeyemhando yeField-Effect Transistor (FET).a MOSFETine gedhi resimbi, oxide insulating layer (kazhinji Silicon Dioxide SiO₂) uye semiconductor layer (kazhinji silicon Si). Nheyo yekushanda ndeyekudzora gedhi voltage kushandura munda wemagetsi pamusoro pepamusoro kana mukati meiyo semiconductor, nokudaro kudzora ikozvino pakati pechitubu uye dhizaini.
MOSFETsinogona kuiswa mumhando mbiri huru: N-chiteshiMOSFETs(NMOS) uye P-chiteshiMOSFETs(PMOS). MuNMOS, kana magetsi egedhi ari akanaka maererano nekwakabva, n-type conducting channels inoumbwa pane semiconductor surface, ichibvumira maerekitironi kuyerera kubva kutsime kuenda kumvura. MuPMOS, kana gedhi regedhi risina kunaka maererano nekwakabva, p-type conducting channels inoumbwa pane semiconductor pamusoro, ichibvumira maburi kuyerera kubva kutsime kuenda kumvura.
MOSFETsane mabhenefiti akawanda, akadai seyakanyanya kupinza impedance, ruzha rushoma, kuderera kwesimba rekushandisa, uye nyore kusanganisa, saka anoshandiswa zvakanyanya mumaseketi eanalogi, maseketi edhijitari, manejimendi emagetsi, magetsi emagetsi, masisitimu ekutaurirana, uye mamwe minda. Mumaseketi akabatanidzwa,MOSFETsndiwo mayuniti akakosha anoumba CMOS (Complementary Metal Oxide Semiconductor) logic maseketi. Maseketi eCMOS anosanganisa zvakanakira NMOS nePMOS, uye anoratidzirwa nekushomeka kwesimba rekushandisa, kumhanya kwakanyanya uye kubatanidzwa kwakanyanya.
Pamusoro pe,MOSFETsinogona kuiswa muchikamu chekusimudzira-rudzi uye depletion-mhando zvichienderana nekuti nzira dzavo dzekuitisa dzakafanoumbwa. Enhancement typeMOSFETmugedhi voltage i zero kana chiteshi chisiri conductive, inoda kuisa imwe gedhi voltage kuti iite conductive chiteshi; apo depletion typeMOSFETmugedhi voltage i zero kana chiteshi chatova conductive, gedhi voltage rinoshandiswa kudzora conductivity yemugero.
Muchidimbu,MOSFETis a field effect transistor yakavakirwa pane simbi oxide semiconductor chimiro, iyo inogadzirisa ikozvino pakati pechitubu uye dhiza nekudzora gedhi voltage, uye ine huwandu hwakawanda hwekushandisa uye yakakosha yehunyanzvi kukosha.
