Kev piav qhia: Thaum lub peev xwm ntog mus txog -fermi peev xwm, qhov kev hloov pauv ntawm qhov chaw tshwm sim. Lub rooj vag voltage uas coj cov kev hloov pauv no hu ua qhov pib voltage. Kev piav qhia: Nto inversion tshwm sim thaum lub rooj vag voltage sib npaug rau qhov pib voltage.
qhov ntsuas hluav taws xob yog dab tsi?
qhov ntsuas hluav taws xob yog qhov hluav taws xob siv nruab nrab ntawm lub rooj vag thiab qhov chaw ntawm MOSFET uas xav tau los tig lub cuab yeej rau cov kab thiab qhov chaw ua haujlwm saturation Kev tshuaj xyuas hauv qab no yog los txiav txim siab qhov pib voltage ntawm N-channel MOSFET (tseem hu ua N-MOSFET).
Yuav ua li cas ntawm qhov ntsuas hluav taws xob?
Qhov pib qhov hluav taws xob, feem ntau luv luv li Vth, ntawm qhov cuam tshuam ntawm qhov cuam tshuam (FET) yog qhov tsawg kawg nkaus qhov rooj-rau-qhov voltage V GS(th) uas xav tau los tsim kev coj ua txoj kev nruab nrab ntawm qhov chaw thiab qhov dej ntws Nws yog ib qho tseem ceeb scaling kom muaj zog efficiency.
txhais tau li cas los ntawm qhov pib voltage Mcq?
Qhov pib voltage nyob ntawm: Qhov kev ua haujlwm sib txawv ntawm lub rooj vag thiab channel, Lub rooj vag hluav taws xob tiv thaiv kom hloov qhov chaw muaj peev xwm, Lub rooj vag hluav taws xob tiv thaiv kom them tus nqi depletion thiab cov nqi tas hauv rooj vag oxide.
qhov ntsuas hluav taws xob ntsuas li cas?
Qhov koj yuav tsum tau txiav txim siab qhov pib qhov hluav taws xob yog siv qhov sib npaug ntawm cov dej ntws tam sim no ua haujlwm ntawm lub rooj vag rau qhov hluav taws xob VGS ntawm VDS saturation cheeb tsam. Lub cheeb tsam saturation yog txhais los ntawm VDSsat=> VGS-Vth Nws yog hu ua txoj kev hloov pauv ntawm qhov ntws tawm tam sim no.
