Tswv yim rau xaiv Crystal Transistor

Cov lus qhia rau kev xaiv siv lead ua transistor

Nws yog ib qho tsim nyog kom nkag siab txog hom thiab cov khoom siv ntawm cov transistors, feem ntau siv yog NPN thiab PNP. Ob hom transistors no muaj cov kev cai sib txawv rau qhov voltage polarity thaum ua haujlwm, yog li ob hom transistors tsis tuaj yeem hloov nrog ib leeg. Triode cov ntaub ntawv suav nrog germanium thiab silicon cov ntaub ntawv, thiab qhov sib txawv ntawm lawv ua ntej yog qhov voltage sib txawv.

Nyob rau hauv ib qho amplification Circuit Court, yog tib hom germanium raj siv los hloov tib hom silicon raj, thiab vice versa, nws yog feem ntau txais, tab sis tsim nyog yuav tsum tau hloov kho rau lub hauv paus bias voltage. Vim tias lawv qhov pib qhov hluav taws xob sib txawv, kev tsom xam tshwj xeeb yuav tsum tau ua los txiav txim siab seb cov khoom sib txawv ntawm cov transistors tuaj yeem hloov pauv hauv cov mem tes circuits thiab hloov circuits, thiab qhov muag tsis pom kev hloov pauv tsis raug tso cai.

Tsuas muaj peb kauj ruam los xaiv Field-effect transistor:

Xaiv qhov tsim nyog channel (N channel lossis P channel)

Txiav txim siab qhov ntsuas tam sim no ntawm Field-effect transistor. Tom qab xaiv qhov ntsuas tam sim no, xam qhov kev poob qis.

Txhawm rau txiav txim siab qhov xav tau thermal, cov neeg tsim qauv yuav tsum xav txog ob qho xwm txheej phem tshaj plaws thiab lub ntiaj teb tiag tiag thaum tsim. Nws feem ntau pom zoo kom suav rau qhov xwm txheej phem tshaj plaws, vim qhov tshwm sim no muab kev nyab xeeb ntau dua thiab ua kom ntseeg tau tias lub kaw lus yuav tsis poob.
