Kodi ndi transistor?

Kamodzi wotchedwa transistor wailesi, koma ndife nkhani amapita pa wailesi. Nanga izo transistor ndi momwe ntchito.

Pali gulu la zipangizo katundu wawo wotchedwa semiconductors. The amadziwika ndi madutsidwe awo - kungakhale monga wochititsa magetsi, ndi dielectrics, i.e. insulators ndi makhalidwe magetsi.

Apa ndi kugwiritsidwa ntchito kuti transistor - ndi michenga yopangira zida zamagetsi chipangizo, amene chimagwiritsidwa ntchito mu mafakitale ndi kutumikira maziko pafupifupi onse zamagetsi zamakono.

Popanda kugwira luso kupanga, mitundu transistor, ntchito yawo, monga kuona kuti pali mitundu yosiyanasiyana ya transistors, mwachitsanzo, npn transistor. Dzina anapatsidwa chifukwa cha kugwiritsidwa ntchito ndi mtundu wa conduction. Zomwe zanenedwa kale zokwanira kupita luso yopanga ndipo zosiyanasiyana transistors Sapita.

Kodi ndi transistor? Bukuli lakonzedwa kulamulira magetsi, amapanga anapangidwa zitsulo kapena pulasitiki nyumba ndipo ali malo atatu, anaitana emitter, m'munsi, wokhometsa. Monga dzina akunena, anapeza pangano: emitter limatulutsa ma elekitironi, amazilamulira Mariya, wokhometsa amatenga iwo. Zonsezi zimachititsa chichitike mkati transistor lapansi.

Kumvetsa mmene transistor, taonani wosalira zambiri Mwachitsanzo - mpopi.

Iye ali malo atatu - chimodzi pa nthawi mu utuluke wapampopi madzi, mosiyana anatsanulira kuchokera wapampopi, ndi valavu lachitatu amene akulamulira ntchito Kireni lapansi. Pamene vavu tidutse madzi umayenda momasuka kudzera vavu pamene vavu chatsekedwa, madzi si loyenda. Ichi ndi onyenga a munthu mwa njira ya momwe transistor ntchito. Izi mode ntchito amatchedwa Keyword - transistor anatsegula - loyenda ya magetsi, kapena lotseka, ndiye panopa sukupita. Kutsegula m'munsi mwa transistor ndi imapatsidwa mphamvu pamene voteji ali, transistor ndi lotseguka, ngati ayi, ndiye anatseka. Chilichonse chimachitika monga faucet, ndi vavu ndi lotseguka - utuluke madzi, vavu chatsekedwa - palibe madzi.

Pamwamba anali ankaona transistor pamene ntchito ngati makiyi, kapena adatsekedwa kapena lotseguka. Komabe, pali modes ena a ntchito. Kachiwiri mu Mwachitsanzo, taganizirani wapampopi. Ngati pang'ono pang'ono kutsegula vavu, madzi mpopi azidzayenda mosalekeza ndi kuthamanga kwa madzi kudzayesedwa mmene tinatsegula wapampopi.

Za ntchito yomweyo mu transistor lapansi. Pa maziko ake amalandira voteji, umathandiza, ndipo kudzera ndi panopa. Mwa kusinthasintha ukulu wa voteji pa tsinde akhoza lizilamuliridwa kuchuluka kwa panopa likuyenderera mu transistor lapansi. Complete fanizo udindo wa valavu pa faucet oposa ndi lotseguka - utuluke za madzi (i.e., panopa kwa transistor); zochepa lotseguka - zochepa madzi oyenda (zatsopano transistor). transistor iyi akutchedwa amplifying ntchito pamene ntchito voteji yaing'ono ntchito maziko a akhoza lizilamuliridwa panopa kwambiri, mgodi zochotseka.

Pomaliza, tisaiwale kuti transistors akhoza osiyanasiyana, onse nthawi imene nkhaniyo ntchito ndi kupanga. Iwo zingasiyane mu mphamvu, akhoza kusamalira ndi kudutsa otaya yokulirapo ya magetsi. The transistors angakhale osiyana ntchito kamangidwe. Pali modes zina transistors yosiyana zimene takambirana. Koma lingaliro zina za mmene transistor amaperekedwa pamwamba.

Chirichonse chimene chakhala pozungulira, koma limachititsa kumvetsa ntchito transistor lapansi. Ndipotu transistor kwenikweni ovuta kwambiri. Pali zoikamo wapadera, zomwe mungathe kugwiritsa ntchito mitunduyi kuwerengera ndi kuyatsa mode akufuna, koma kuti ndi mitu kukambirana nkhani ina.
