A na u tseba tlhaloso ea MOSFET?

MOSFET, e tsejoang e le Metal-Oxide-Semiconductor Field-Effect Transistor, ke sesebelisoa sa elektronike se sebelisoang haholo seo e leng sa mofuta oa Field-Effect Transistor (FET).MOSFETe na le heke ea tšepe, lera la oxide insulating (hangata Silicon Dioxide SiO₂) le lera la semiconductor (hangata silicon Si). Molao-motheo oa ts'ebetso ke ho laola motlakase oa heke ho fetola tšimo ea motlakase holim'a metsi kapa ka hare ho semiconductor, ka hona ho laola hona joale pakeng tsa mohloli le metsi.

MOSFETse ka aroloa ka mefuta e 'meli e meholo: N-channelMOSFETs(NMOS) le P-channelMOSFETs(PMOS). Ho NMOS, ha motlakase oa heke o le motle mabapi le mohloli, liteishene tsa ho tsamaisa li-n-type li thehoa holim'a semiconductor holim'a metsi, ho lumella li-elektronike ho phalla ho tloha mohloling ho ea ho drain. Ho PMOS, ha motlakase oa heke o le mpe mabapi le mohloli, liteishene tse tsamaisang mofuta oa p li thehoa holim'a semiconductor, ho lumella masoba ho phalla ho tloha mohloling ho ea ho drain.

MOSFETsli na le melemo e mengata, joalo ka ho kenella ho phahameng, lerata le tlase, tšebeliso e tlase ea matla, le boiketlo ba ho kopanya, kahoo li sebelisoa haholo lipotolohong tsa analoge, lipotoloho tsa dijithale, taolo ea matla, lisebelisoa tsa elektroniki tsa motlakase, lits'ebetso tsa puisano le likarolo tse ling. Ka li-circuits tse kopaneng,MOSFETske likarolo tsa mantlha tse etsang li-circuits tsa logic tsa CMOS (Complementary Metal Oxide Semiconductor). Li-circuits tsa CMOS li kopanya melemo ea NMOS le PMOS, 'me li khetholloa ka tšebeliso e tlaase ea matla, lebelo le phahameng le kopanyo e phahameng.

Holim'a moo,MOSFETse ka aroloa ka mofuta oa ntlafatso le mofuta oa depletion ho latela hore na likanale tsa tsona li entsoe esale pele. Mofuta oa ntlafatsoMOSFETka heke gagamalo ke zero ha kanaleng e sa conductive, ho hlokahala hore ho sebelisa e itseng heke gagamalo ho theha mocha conductive; nakong ea mofuta oa depletionMOSFETka motlakase oa heke ke zero ha mocha o se o ntse o khanna, motlakase oa heke o sebelisoa ho laola conductivity ea mocha.

Ka kakaretso,MOSFETke tšimo phello transistor e thehiloeng tšepe oxide semiconductor sebopeho, e leng laola hona joale pakeng tsa mohloli le drain ka ho laola heke gagamalo, 'me o na le mefuta e fapaneng ya dikopo le bohlokoa botekgeniki bohlokoa.
