Matšoao a MOSFET a atisa ho sebelisoa ho bontša kamano ea eona le litšobotsi tsa eona tse sebetsang potolohong.MOSFET, lebitso le feletseng Metal Oxide Semiconductor Field Effect Transistor (Metal Oxide Semiconductor Field Effect Transistor), ke mofuta oa lisebelisoa tsa semiconductor tse laoloang ke motlakase, tse sebelisoang haholo lipotolohong tsa elektroniki. .
Li-MOSFET li arotsoe haholo-holo ka lihlopha tse peli: N-channel MOSFETs (NMOS) le P-channel MOSFETs (PMOS), e 'ngoe le e 'ngoe e na le letšoao le fapaneng. E latelang ke tlhaloso e qaqileng ea mefuta ena e 'meli ea matšoao a MOSFET:
N-Channel MOSFET (NMOS)
Letšoao la NMOS hangata le emeloa e le setšoantšo se nang le lithapo tse tharo, e leng heke (G), drain (D), le mohloli (S). Letšoaong, heke hangata e ka holimo, ha mokelikeli le mohloli o ka tlaase, 'me drainage e atisa ho ngoloa e le pinana e nang le motsu e bontšang hore tataiso e ka sehloohong ea phallo ea hona joale e tsoa mohloling ho ea ho drain. Leha ho le joalo, ke habohlokoa ho hlokomela hore litšoantšong tsa sebele tsa potoloho, tataiso ea motsu e ka 'na ea se ke ea lula e lebisa ho drain, ho itšetlehile ka hore na potoloho e hokahane joang.
P-channel MOSFET (PMOS)
Matšoao a PMOS a tšoana le NMOS ka hore a boetse a na le setšoantšo se nang le lithapo tse tharo. Leha ho le joalo, ho PMOS, tataiso ea motsu ka letšoao e ka 'na ea fapana hobane mofuta oa mochine o fapane le NMOS (likoti ho e-na le li-electrone), empa hase matšoao ohle a PMOS a ngotsoeng ka ho hlaka ka tataiso ea motsu. Hape, heke e teng ka holimo 'me drain le mohloli li fumaneha ka tlase.
Mefuta e sa tšoaneng ea Matšoao
Ho bohlokoa ho hlokomela hore matšoao a MOSFET a ka ba le mefuta e itseng ho software kapa litekanyetso tse fapaneng tsa setaele sa potoloho. Mohlala, matšoao a mang a ka siea metsu ho nolofatsa kemelo, kapa a khetholla lipakeng tsa mefuta e fapaneng ea li-MOSFET ka mefuta e fapaneng ea mela le mebala e tlatsitsoeng.
Litlhokomelo ts'ebetsong e sebetsang
Lits'ebetsong tse sebetsang, ntle le ho lemoha matšoao a MOSFET, ho boetse hoa hlokahala ho ela hloko polarity ea bona, boemo ba motlakase, bokhoni ba hona joale le likarolo tse ling ho netefatsa khetho e nepahetseng le tšebeliso. Ntle le moo, kaha MOSFET ke sesebelisoa se laoloang ke motlakase, ho hlokahala hore ho be le tlhokomelo e khethehileng ho mehato ea taolo le ts'ireletso ea heke ha o rala potoloho ho qoba ho senyeha ha heke le liphoso tse ling.
Ka kakaretso, letšoao la MOSFET ke kemelo ea eona ea mantlha potolohong, ka ho tsebahatsa matšoao a ka utloisisa mofuta oa MOSFET, khokahano ea phini le litšobotsi tsa ts'ebetso. Leha ho le joalo, lits'ebetsong tse sebetsang, ho boetse hoa hlokahala ho kopanya litlhoko tse khethehileng tsa potoloho le lisebelisoa tsa lisebelisoa bakeng sa ho hlahlojoa ka botlalo.
