Field effect transistor

Lub ntsiab lus ntawm "field effect" yog tias txoj haujlwm ua haujlwm ntawm lub transistor no yog ua raws li cov hluav taws xob hauv hluav taws xob ntawm lub semiconductor.

Field effect transistor Ib lub transistor uas ua haujlwm ntawm lub hauv paus ntsiab lus ntawm cov nyhuv teb. Field effect transistors nyob rau hauv lem muaj ob lub ntsiab: Junction FETs (JFETs) thiab Hlau-Oxide Semiconductor FETs (MOS-FETs). Tsis zoo li BJT, FETs tsuas yog siv hluav taws xob los ntawm ib hom cab kuj (feem ntau cov cab kuj) thiab yog li ntawd kuj hu ua unipolar transistors. Nws belongs rau cov khoom siv hluav taws xob tswj hluav taws xob semiconductor thiab muaj qhov zoo ntawm cov kev tawm tswv yim zoo, tsis tshua muaj suab nrov, tsis muaj zog noj, loj dynamic ntau, kev sib koom ua ke yooj yim, tsis muaj kev puas tsuaj ntxiv, thiab thaj chaw ua haujlwm zoo.

Cov nyhuv teb yog los hloov cov kev taw qhia lossis qhov loj ntawm daim ntawv thov hluav taws xob perpendicular mus rau qhov chaw ntawm cov khoom siv hluav taws xob los tswj qhov ntom ntom lossis hom ntawm cov neeg nqa khoom feem ntau hauv cov txheej txheem semiconductor (channel). Nws yog voltage-modulated tam sim no nyob rau hauv cov channel uas nws khiav hauj lwm tam sim no yog thauj los ntawm feem ntau cov cab kuj nyob rau hauv lub semiconductor. Xws li ib tug transistor uas tsuas yog ib hom polar cab kuj koom nyob rau hauv conduction kuj hu ua ib tug unipolar transistor. Piv nrog rau bipolar transistors, teb cov nyhuv transistors muaj cov yam ntxwv ntawm siab input impedance, tsis tshua muaj suab nrov, siab txwv zaus, tsawg zog noj, yooj yim manufacturing txheej txheem thiab zoo kub yam ntxwv. Lawv tau dav siv nyob rau hauv ntau yam amplifier circuits, digital circuits thiab microwave circuits. Tos. Silicon-raws li hlau 0-oxide-semiconductor field effect transistors (MOSFETs) thiab gallium arsenide-based Schottky barrier field effect transistors (MESFETs) yog ob qho tseem ceeb tshaj plaws ntawm cov nyhuv transistors. Lawv yog cov khoom siv yooj yim ntawm MOS LSI thiab MES ultra-high-speed integrated circuits.
