FETs iyo sida ay u shaqeeyaan

FETs ku jira hindisooyin Semiconductor kuwa, mabda'a hawlgalka ah oo ku salaysan iska caabin ah oo duurka ku transverse korontada ee isbedbeddelka ee wax Semiconductor ah.

feature The garan noocan ah ee qalabka waa in transistors saamayn field leeyihiin faa'iido ah danab sare iyo iska-caabbinta sare si ay u soo socda ee.

Meelahaas waxaa qalabka Abuuridda koronto oo kaliya ka qaadaan sidayaal ah nooca la mid ah ayaa ku lug leh (electrons).

Waxaa jira laba nooc oo FETs:

- isagoo qaab-dhismeedka TIR ah, i.e. biraha, soo raacay by dielectric ah, ka dibna Semiconductor ah (MIS);

- Maareynta la pn-isgoyska.

Dhismaha transistor ugu fudud saamayn field ka mid ah waslad khafiifa oo wax Semiconductor hal pn-guurka kaliya ee xarunta iyo ohmic xiriirada on geesaha ka dhigay.

koronto ee qalab noocan oo kale ah taas oo ah qabashada sidayaal lacag channel waxaa loo yaqaan il iyo koronto on kaas oo electrodes ka ah ka channel - godka.

Mararka ay dhacdo in qalab muhiim ah oo awood badan sida baxay si. Sidaa darteed, inta lagu guda jiro dayactirka qalabka korontada inta badan waxaa lagama maarmaan ah si loo hubiyo FET ah.

Si taas loo sameeyo this, qalab vypayat, maxaa yeelay, ma awoodi doonaan in ay hubiyaan Bannaanka electronic. Ka dibna, raacaya tilmaamaha gaarka ah, sii soco ilaa magalka.

transistors saamayn Field waxay leeyihiin laba hababka qalliinka - firfircoon oo muhiim ah.

hawlgalka transistor - waa mid ka mid ah taas oo transistor waa in labada dal - in si buuxda u furan yahay ama si buuxda u xiran. Laakiin dawladda dhexe this, marka qayb furan yahay qayb ahaan ka maqan.

In kiiska ugu fiican, marka transistor waa "furo", i.e. waa waxa loogu yeero hab robab ah, impedance dhexeeya boosteejada "godka" iyo "isha" eber.

Power khasaaraha inta lagu guda jiro danab gobolka furan u muuqataa wax soo saarka (ma lamid eber) ee qadarka hadda. Sidaas awgeed, dhereg awood waa eber.

In hab xadka ayaa, i.e. markii blocks transistor ah, iska caabin ah u dhexeeya "/ il Jidka godka" deduces ay u egtahay in ay xad la'aan. dhereg Power ee gobolka xiran waa wax soo saarka ee danab ee guud ahaan qiimaha hadda loo siman yahay eber. Iyadoo la raacayo, awood khasaaro = 0.

Waxaa soo baxday in qaabka ugu muhiimsan ee transistors khasaaro xoog waa eber.

In dhaqanka, in transistor bannaan, si dabiici ah, qaar ka mid ah iska caabin ah "Jidka godka / ilaha" joogi doonaan. Iyada oo transistor u xiran yihiin kuwaas gunaanad qiimo yar yahay hadda weli dhacdo. Sidaas awgeed, khasaaro xoog in hab a ma guurto ah in transistor ah waa ay yar tahay.

A dynamically, marka transistor xiran yahay ama la furay, oo kordhiyey ay gobolka toosan dhibic hawlgalka halkaas oo hadda ku dhex maraya transistor ah, conventionally waa kala bar godka hadda. Laakiin danab "saxanka / il" inta badan wuxuu gaartaa bar qiimaha ugu badnaan. Sidaas awgeed, hab qoondaynta firfircoon bixisaa transistor khasaaro xoog weyn, taas oo yaraynaysa "maya" sifooyinka cajiib ah hab muhiim ah.

Laakiin, markeeda, gaadhista dheer transistor ee hab firfircoon ayuu uga yar yahay dhererka joogaan hab ma guurto ah. Sidaas darteed, wax ku oolnimada stage transistor kuwaas oo ka hawlgala bedesheen hab ah, waa mid aad u sarreeya oo waxay noqon kartaa sagaashan saddex ilaa sagaashan sideed boqolkiiba.

transistors Field saamayn taas oo ka shaqeeya hab kor ku xusan, waxaa ku filan si ballaaran loo isticmaalo in unugyada awood diinta, a ilaha awooda garaaca wadnaha, marxaladaha soo saarka ee laliska gaar ah iyo si bixi.
