Mabaadii'da ka hawlgala ee transistor ah

Transistor - qalab in waddaa on semiconductors ee korontada ku. Waxaa loogu talagalay dadka diinta iyo cod ee signallo koronto. Waxaa jira laba nooc oo ah qalabka: transistor bipolar ah iyo transistor ku unipolar ama beer.

Haddii transistor ku jira laba nooc oo sidayaal lacag shuqul isku mar - godad iyo electrons, waxa loo yaqaan bipolar. Haddii transistor waa nooca lacag hal kaliya, waa unipolar.

Bal qiyaas shaqo ee biyaha tuubada caadiga ah. Jeestay bool - socodka biyaha kor u kacay, ayuu soo leexday iyadoo jidka oo kale - si loo yareeyo ama joojiyo socodka. Xaqiiqo ahaan tani waa mabda'a of hawlgalka transistor ah. electrons Kaliya halkii il biyo ah dal therethrough. Mabda'a hawlgalka nooca transistor-cirifoodka waxaa lagu gartaa xaqiiqada ah in iyada oo qalab this electronic jira laba nooc oo awood yihiin. Waxay kala qaybsan yihiin sare, ama aasaasi ah oo yar, ama maamulaha. War sidee gacanta hadda ku saameeyaa awoodda xoogga ugu weyn. Tixgeli transistor saamayn beer. Mabda'a ah in ay hawlgalka waa ka dadka kale ee kala duwan. Waxaa ag maraaba mid kaliya wax soo saarka ee hadda taas oo ku xiran tahay daarmayaay'e beerta electromagnetic.

transistor The bipolar laga sameeyey oo 3 layers of Semiconductor ah, iyo sidoo kale, ugu muhiimsan, labada PN-isgoosyada. Waxaa lagama maarmaan ah in la kala saaro PNP iyo guurka NPN iyo, Sidaa darteed, iyo transistors. semiconductors Kuwan waxaa talantaalli electron iyo godka tabinta.

transistor The bipolar waxay leedahay saddex boosteejada. la xiriir saldhigga Tani, ka tago lakabka xarunta, iyo laba electrodes at geesaha - emitter iyo ururiyaha. Marka la barbar dhigo labadan electrodes xad-dhaaf ah lakabka saldhig waa mid aad u dhuuban. Dhinacyada cidhifyada gobolka transistor ee Semiconductor ee ma aha symmetrical. lakabka Semiconductor ah u amro dhinaca ururiyaha si qalliin saxda ah ee qalabka waa in la sii dayn wax yar, laakiin waa ka sii dhumuc sida dhinaca emitter ah marka la barbar dhigo.

mabaadi'da hawlgalka transistor ku salaysan yihiin geeddi socodka jirka. Aan la PNP model shaqeeyaan. model NPN shaqayn doona mid ah polarity ee danab u dhexeeya xubno ka aasaasiga ah sida ururiyaha ah iyo emitter ah mooyee. Waxa ay noqon doontaa in jihada ka soo horjeedda.

nooca P-Maandooriyaha kooban god ama udhigo si togan ku amray. mukhaadaraadka nooca N-ka kooban electrons xun lagu soo eedeeyay. In tirada transistor godadkii ee gobolka F Ilaaheenna ah waa inta ka badan tirada electrons in N.

Marka aad ku xidhi il danab u dhexeeya qaybaha sida emitter iyo ururiyaha oo ka mid ah mabaadiida hawlgalka transistor ku salaysan yihiin xaqiiqda ah in godadkii soo jiita baallaha oo uu soo urursado meel u dhow emitter ah. Laakiin hadda ma tagaan. duurka oo korontada ka il danab uusan gaari ururiyaha sababtoo ah lakabka emitter Semiconductor qaro iyo lakabka Semiconductor salka.
Markaas xirmaan il danab a isku dhafan oo kala duwan oo xubno ka, kuwaas oo saldhig iyo emitter. Haddaba godad loo soo diray in ay database oo ay bilaabaan si ay ula falgalaan electrons ah. Qaybta dhexe ee salka la cokan rito. Natiijadu waxay tahay laba hadda. Big - ka emitter si ururinaysa, yar - ka ee saldhiga ah in emitter ah.

Iyada oo la kordhiyo danab ee database ee lakabka N noqon doonaan godad xitaa more, si loo kordhiyo hadda saldhigga, emitter hadda wax yar kor u kici doono. Taas macnaheedu waa in isbedel yar oo saldhig hadda si dhab ah oo ku filan maqalka emitter hadda. Natiijadu waxay tahay signal koritaanka in transistor bipolar ah.

Tixgeli mabaadi'da transistor ah ku xiran tahay hab qalliinka. Kala hab caadi ah u firfircoon, hab firfircoon bedelka, damaysay, hab xadka.
In hab firfircoon, Isgoyska emitter waa la furi waxayna xidhay Isgoyska ururiyaha. In hab inversion ah, wax kasta oo dhacaya on lid ku ah.
