MOSFET: chiito uye yezvinoreva musimboti

Kudzidza ehupfumi ane zvinhu zvakadai somunhu semiconductor, akabvumira kuti echimurenga matongo. Over nguva pane zvigadzirwa kuti kutengeswa zvibereko diodes, mos transistors, thyristors nezvimwe zvinhu. Ivo zvinobudirira akatsiviwa Vacuum sepombi uye kubvumirwa kuona kupfuura ushingiwo pfungwa. Semiconductor zvinoriumba anoshandiswa munyaya zvose zvoupenyu hwedu. Anotibatsira ribude yakawanda mashoko nemhaka makombiyuta dzavo anogadzirwa, tepi vanyori, materevhizheni, etc.

Sezvo michina wokutanga transistor, uye zvakanga muna 1948, vakapfuura nguva refu. Paiva Misiyano chaikosha ichi: pfungwa germanium, nesilicon, munda-zvazviri transistor kana MOSFET. Vose vari zvinowanzoshandiswa zvemagetsi michina. The kudzidza zvivako zviri semiconductors haangarevi kumisa munguva yedu.

Zvidzidzo izvi zvakatungamirira kuti kwaita mudziyo yakadaro somunhu MOSFET. Nheyo kushanda nayo inobva pakuti yemagetsi munda (saka rimwe zita - munda) dzinosiyana kuti conductivity pakati pemvura semiconductor rukoko pamuganhu pamwe dielectric. pfuma iyi inoshandiswa zvemagetsi nematunhu zvinangwa zvakasiyana-siyana. Mos transistor ane chimiro iyo anobvumira kuti kudzikisa kurwisa pakati zvaimutambisira uye anokonzera pasi pokudzora kwomudzimu kuzvidzora chiratidzo substantially kuti razero.

ehupfumi Its zvakasiyana nedambudziko "mukwikwidzi". Pavanondirwisa kuona kukura kwebasa chikumbiro chacho.

• High waivako zvinoitwa miniaturizing ari sekristaro pacharo uye ayo akasiyana zvivako. Izvi imhaka nematambudziko maindasitiri kugadzirwa. Pari, crystals anobudiswa ane 0,06 micron suwo.
• A duku Kuchinja capacitance inoita mano izvi kushanda dzakakwirira maitikiro matunhu. Somuenzaniso, imwe LSI kwavo kushandiswa rave zvinobudirira kushandiswa Mobile yokukurukurirana.
• Anenge razero nemishonga, iro rine MOSFET iri pachena mamiriro, rinogona kushandiswa zvemagetsi kiyi. Vanogona kushanda mumatunhu kuti generating yakakwirira maitikiro anonongedzera kana kuti Kukunda zvinhu zvakadai woshanda amplifiers.
• Simba mano ichi mhando zvave vakabudirira kushandiswa simba modules uye kunogona kushandiswa induction redunhu. Muenzaniso wakanaka wavo kushandiswa kungava kuti inverter.

Kana mazano uye kushanda pamwe zvinhu izvi zvinokosha kufunga zvimwe. MOSFETs vane hanya overvoltage uye kuzvishandura nyore kukundikana. The inductance matunhu inowanzoshandiswa mukuru-nokukurumidza Schottky diodes kuti rimire pamusoro neizvi voltage kupomba, kunoitika munguva nokuchinja.

Tarisiro vashandise mano aya zvikuru guru. Kuvandudza mabikirwo gadzira wavo uri nzira yokuderedza sekristaro (shutter scaling). Zvishoma nezvishoma zvichiitika namano kuti anogona kubata Motors kupfuura simba.
