IGFET (Insulated gate field effect transistor): Lub rooj vag yog sib cais los ntawm cov channel los ntawm ib txheej ntawm silicon dioxideuas yog ib qho insulator kom ntseeg tau tias lub rooj vag raug cais tawm ntawm ob qho tib si. thiab ntws.
Dab tsi cais lub rooj vag thiab channel hauv MOSFET?
MOSFET ua haujlwm zoo ib yam li JFET's tab sis muaj lub rooj vag lub rooj vag uas yog hluav taws xob cais tawm ntawm cov channel conductive.
Dab tsi yog qhov thaiv qhov rooj qhov cuam tshuam transistor lossis Igfet?
Lub rooj vag hluav taws xob FET, tseem hu ua hlau oxide semiconductor field effect transistor (MOSFET), zoo ib yam li JFET tab sis nthuav tawm ib qho kev tawm tsam loj dua vim yog txheej nyias ntawm silicon dioxide uas yog siv los insulate lub rooj vag ntawm lub semiconductor channel.
Yuav ua li cas channel tsim hauv MOSFET?
Kev ua haujlwm ntawm MOSFET yog nyob ntawm MOS capacitor. MOS capacitor yog qhov tseem ceeb ntawm MOSFET. Lub semiconductor nto nyob rau hauv qab oxide txheej uas yog nyob nruab nrab ntawm qhov chaw thiab ntws terminals. … Yog tias peb siv qhov tsis zoo voltage, lub qhov channel yuav raug tsim nyob rau hauv txheej oxide.
xov xwm hauv MOSFET yog dab tsi?
N-Channel MOSFET muaj thaj tsam N-channel nyob rau hauv nruab nrab ntawm qhov chaw thiab qhov chaw nres nkojNws yog plaub lub davhlau ya nyob twg muaj cov terminals li rooj vag, ntws, qhov chaw, cev. Nyob rau hauv hom Field Effect Transistor, qhov ntws thiab qhov chaw yog hnyav heev n + cheeb tsam thiab lub substrate lossis lub cev yog P-hom.
