Kev qhia dav dav rau subthreshold slope subthreshold slope Lub subthreshold txoj kab nqes yog feature ntawm MOSFET tus yam ntxwv tam sim no-voltage. Hauv cheeb tsam subthreshold, tus cwj pwm ntws tam sim no - txawm tias raug tswj los ntawm lub rooj vag davhlau ya nyob twg - zoo ib yam li qhov exponentially txo tam sim no ntawm ib tug pem hauv ntej biased diode. https://en.wikipedia.org › wiki › Subthreshold_slope
Subthreshold nqes hav - Wikipedia
(swing) is S=(d(log10Ids)/dVgs)-1. Los yog los ntawm cov phiaj xwm saum toj no, ntawm Vgs qis heev, coj cov txiaj ntsig ntawm qhov tseem ceeb ntawm Ids nrog rau Vgs thiab tom qab ntawd hloov pauv tus nqi tshwm sim.
txhais tau li cas los ntawm subthreshold viav vias?
Lub viav vias subthreshold txhais tau tias yog lub rooj vag voltage xav tau . hloov pauv cov dej ntws los ntawm ib qho kev txiav txim siab, ib qho . xyooj. Nyob rau hauv MOSFET, lub subthreshold viav vias yog txwv. rau (kT/q) ln10 los yog 60 mV/dec ntawm chav tsev kub, thiab nrog.
Dab tsi yog qhov subthreshold slope factor?
Lub subthreshold txoj kab nqes yog ib qho ntawm a MOSFET tus yam ntxwv tam sim no-voltage . … Ib xyoo caum (xyoo caum) sib raug mus rau 10 npaug ntawm qhov ntws tawm tam sim no ID. Ib lub cuab yeej ua cim los ntawm txoj kab nqes qis qhia txog kev hloov pauv sai ntawm kev tawm (tsawg tam sim no) thiab rau (siab tam sim no) xeev.
Dab tsi yog qhov tseem ceeb ntawm kev hloov pauv hloov pauv?
Lub viav vias subthreshold yog qhov tseem ceeb parameter hauvua qauv rau cov tsis muaj zog inversion regime, tshwj xeeb tshaj yog rau high-tau analog applications, imaging circuits, thiab low-voltage applications.
Lub subthreshold tam sim no sib txawv li cas nrog lub rooj vag voltage?
Qhov kev txo qis txhais tau tias tsawg dua lub rooj vag hluav taws xob viav vias hauv qab qhov pib kom tig lub cuab yeej tawm, thiab raws li qhov kev hloov pauv hloov pauv hloov pauv nrog lub rooj vag voltage (saib MOSFET: Txiav-tawm hom), nws ua ntau dua thiab tseem ceeb dua li MOSFETs ntswsin size.
