A bandgap voltage reference yog qhov ntsuas kub ywj pheej siv hluav taws xob siv dav siv hauv kev sib xyaw ua ke. Nws tsim ib qho hluav taws xob ruaj khov (tsis tu ncua) tsis hais txog kev hloov pauv ntawm cov khoom siv hluav taws xob, kev hloov pauv kub, lossis kev thauj khoom Circuit Court los ntawm lub cuab yeej.
Vim li cas peb thiaj hais qhov sib txawv?
Lub Hom Phiaj ntawm Bandgap siv Circuit Court: Bandgap siv Circuit Court muab qhov tsis tu ncua dc voltage uas tiv thaiv qhov kub thiab txias hloov pauv, suab nrov, lub zog rub tawm, thiab cov khoom siv hluav taws xob hloov pauv.
Dab tsi yog qhov ua tau zoo ntawm qhov ntsuas kub ntawm qhov siv bandgap?
Cov ntaub ntawv hais txog bandgap tuaj yeem ua tiav qhov ntsuas kub li qis li 20 ppm / °C.
Ctat thiab PTAT yog dab tsi?
The ΔVBE thiab V BE cov khoom muaj qhov sib txawv polarity TCs; ΔVBE yog proportional-to-absolute-temperature (PTAT), hos V BE yog complementary-to-absolute-temperature (CTAT). Thaum cov zis summed, V Ref,yog sib npaug rau 1.205 V (silicon bandgap voltage), TC yog qhov tsawg kawg nkaus.
Kuv yuav xaiv qhov siv hluav taws xob li cas?
Xaiv qhov siv
- Puas yog qhov khoom siv hluav taws xob siab heev? …
- Puas yog qhov khoom siv hluav taws xob lossis qhov thauj khoom tam sim no sib txawv? …
- Yuav tsum muaj lub zog ua haujlwm siab? …
- Xaiv koj qhov ntsuas kub ntawm lub ntiaj teb tiag. …
- Ua tiag tiag txog qhov yuav tsum tau muaj tseeb. …
- Qhov khoom siv tiag tiag yog dab tsi? …
- Lub zog siv tau npaum li cas? …
- Ntau npaum li cas load tam sim no?

Thaum twg siv los yog tsis siv?
Ib leeg: ib leeg txhais tau tias "ib ntawm ob"; tsis txhais hais tias "tsis muaj ntawm ob." Siv cov lus qhia ib leeg. Ib yam ua ke nrog lossis; tsis yog ua ke nrog los yog. Koj hais kuv los tsis yog kuv thiab? Tsis yog grammatically tseeb.
Thaum twg siv i.e. thiab thaum twg siv xws li?
I.e. yog ib qho luv luv rau kab lus id est, uas txhais tau tias "uas yog." I.e. yog siv los rov hais dua ib yam dab tsi uas tau hais yav dhau los txhawm rau kom meej nws lub ntsiab lus. E.g. luv luv rau exempli gratia, uas txhais tau tias "
Leej twg tsim lub bandgap voltage siv?
Cov txheej txheem siv bandgap yog ib txoj hauv kev siv ntau tshaj plaws los tsim kom muaj qhov kub thiab txias-yooj yim siv hluav taws xob. Bob Widlar, tus kws tshaj lij hluav taws xob zoo nkauj, tau tsim lub hauv paus rau hnub no lub bandgap voltage references nyob rau hauv lig 1960s.
Thaum twg siv polyacrylamide thiab thaum twg agarose?
Agarose gels siv nrog DNA, vim qhov loj ntawm biomolecules (DNA feem ntau yog ntau txhiab kDa). Rau cov protein gels, polyacrylamide muab daws teeb meem zoo, raws li qhov me me me (50 kDa yog qhov raug) zoo dua rau qhov sib txawv ntawm cov gel.
Thaum twg siv cov khoom siv?
Throughput yog hais txog ntau npaum li cas cov ntaub ntawv tuaj yeem xa los ntawm ib qhov chaw mus rau lwm qhov hauv lub sijhawm. Nws yog siv los ntsuas qhov kev ua tau zoo ntawm hard drives thiab RAM , nrog rau kev sib txuas hauv Is Taws Nem thiab network.
