Txoj kab nqes qis yog ib qho ntawm MOSFET tus yam ntxwv tam sim no-voltage. Nyob rau hauv cheeb tsam subthreshold, qhov ntws tam sim no tus cwj pwm - 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.
Dab tsi yog qhov tseem ceeb ntawm kev hloov pauv hloov pauv?
Lub viav vias subthreshold yog qhov qhov tseem ceeb hauv kev ua qauv ntawm kev tsis muaj zog inversion regime, tshwj xeeb tshaj yog rau cov ntawv thov analog tau zoo, cov duab kos duab, thiab cov ntawv siv hluav taws xob tsawg.
Lub ntsiab lus ntawm kev hloov pauv hloov pauv yog dab tsi?
Subthreshold viav vias (S) yog daim duab ntawm qhov tsim nyog uas txiav txim siab tus cwj pwm ntawm transistor hauv thaj tsam subthreshold. Kev ua tau zoo ntawm cov hlau-oxide-semiconductor-field-effect transistor (MOSFET) yog tsim los ntawm cov thermal voltage (kT/q), uas ua rau qhov theoretical yam tsawg kawg nkaus ntawm S=60mV / xyoo caum.
Dab tsi yog subthreshold swing hauv VLSI?
Lub subthreshold slope yog a feature ntawm MOSFET tus yam ntxwv tam sim no-voltage . … Ib qho kev sim me me viav vias rau qhov ntsuas MOSFET ntawm chav tsev kub yog ~ 70 mV / dec, me ntsis degraded vim luv-channel MOSFET parasitics. Ib xyoo caum (xyoo caum) sib raug rau 10 npaug ntawm qhov ntws tawm tam sim no ID.
Yuav ua li cas thiaj nrhiav tau kuv qhov kev hloov pauv hloov pauv li cas?
Cov lus qhia dav dav rau subthreshold slope (vav) yog S=(d(log10Ids)/dVgs)-1. Los yog los ntawmsaum toj no cov phiaj xwm, ntawm Vgs qis heev, coj cov txiaj ntsig ntawm qhov tseem ceeb ntawm Ids nrog kev hwm rau Vgs thiab tom qab ntawd hloov pauv tus nqi tshwm sim.

Puas yog cov dab dab dab dab dab dab dab dab dab dab dab dab?
Myth: Ib tug dab tshos tsis yog neeg ncaj ncees yog tiasnws haum yog. Fact: Tu siab, qhov no yog ib lo lus tsis tseeb uas tau raug perpetuated los ntawm aversive trainers. Txawm hais tias haum rau lub caj dab kom zoo khawb rau hauv cov tawv nqaij rhiab nyob ib ncig ntawm lub caj dab, uas ua rau muaj kev puas tsuaj loj rau cov thyroid, esophagus, thiab trachea.
Leej twg yog tus tauj ncov viav vias lub npe cim dab tsi?
Lub npe Captain Swing symbolized los yog sawv cev rau kev npau taws ntawm cov neeg ua haujlwm pluag hauv tebchaws Askiv uas xav rov qab mus rau lub tshuab ua ntej hnub uas tib neeg siv zog. Tus tauj ncov loj yog leej twg? Nws cuam tshuam nrog cov neeg ua liaj ua teb thiab kev ua haujlwm ntawm kev tawm tsam ntawm Askiv.
Yuav ua li cas xam subthreshold viav vias?
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.
Lub xeev viav vias yog dab tsi?
Raws li kev txheeb xyuas ua ntej kev xaiv tsa xyoo 2016, kaum peb lub xeev sib tw tshaj plaws yog Wisconsin, Pennsylvania, New Hampshire, Minnesota, Arizona, Georgia, Virginia, Florida, Michigan, Nevada, Colorado, North Carolina, thiab Maine.
Lub viav vias kos valve yog dab tsi?
Nyob hauv viav vias kos li qub, flapper yuav viav vias tawm kom tso cai rau pem hauv ntej ntws ntawm cov kua lossis roj. Thaum nws yog lub sij hawm kom tsis txhob ntws, lub flapper yuav tig rov qab mus rau lub rooj zaum, kaw lub valve tau txais raws li qhov system siab txo.
