Nyob rau hauv qhov tsis ncaj ncees lawm ib qho hluav taws xob tau siv thoob plaws lub cuab yeej xws li hluav taws xob ntawm qhov sib txuas nce. Qhov chaw hluav taws xob siab dua hauv thaj av depletion txo qhov tshwm sim uas cov neeg nqa khoom tuaj yeem sib kis los ntawm ib sab ntawm kev sib tshuam mus rau lwm qhov, yog li qhov cuam tshuam tam sim no txo qis.
Yuav ua li cas thaum pn junction diode rov qab biased?
Thaum lub peev xwm sab nraud tau siv rau p-n hlws ris, qhov barrier txo kom txog thaum nws dhau los ua xoom thaum qhov hluav taws xob sab nraud ntau dua li qhov muaj peev xwm barrier. Thaum qhov hluav taws xob thim rov qab tau nce ntxiv, p-n kev sib tshuam yuav tawg thiab tso cai rau ntau qhov tam sim no dhau los ntawm nws.
Qhov twg ntawm pn hlws ris diode yog siv rau kev thim rov qab?
Rov qab Biased PN Junction. Thaum lub davhlau ya nyob twg zoo ntawm qhov chaw hluav taws xob txuas nrog n-hom cheeb tsam thiabqhov tsis zoo ntawm qhov chaw txuas nrog thaj tsam p-hom. PN kev sib tshuam tau hais tias nyob rau hauv qhov kev hloov pauv tsis zoo.
Dab tsi yog thim rov qab biasing diode?
Hauv tus qauv diode, kev sib tw rau pem hauv ntej tshwm sim thaum qhov hluav taws xob hla lub diode tso cai rau lub ntuj ntws ntawm tam sim no, whereas thim rov qab biasing txhais tau tias ib qhov hluav taws xob hla lub diode nyob rau sab nraud.
Kev sib tw ntawm pn junction diode yog dab tsi?
Lub sij hawm tsis ncaj ncees yog hais txog daim ntawv thov ntawm DC voltage los teeb tsa qee yam haujlwmtej yam kev mob. Los yog thaum lwm qhov chaw ntawm lub zog siv rau P-N hlws ris nws yog hu ua kev tsis ncaj ncees voltage lossis tsuas yog kev tsis ncaj ncees. Txoj kev no yog nce lossis txo qhov cuam tshuam ntawm kev sib tshuam.
