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?
