Kev tsis ncaj ncees rov qab ua rau thaj tsam ntau ntxiv hauv tus PIN diode. Kev piav qhia: Hauv kev tsis ncaj ncees rau pem hauv ntej, qhov kev tawm tsam rau pem hauv ntej yuav txo qis thiab ua raws li hloov pauv hloov pauv. … Piav qhia: Hauv qhov kev tsis ncaj ncees thim rov qab, txheej txheej sab hauv yog tag nrho los ntawm cov txheej txheem depletion. Cov nqi khaws cia ploj mus ua haujlwm zoo li lub capacitor sib txawv.
Thaum tus PIN diode thim rov qab nws ua raws li?
Ntawm xov tooj cua zaus, tus PIN diode ua raws li tus nqi me me lossis ua tus hloov pauv hloov pauv, nyob ntawm DC kev tsis ncaj ncees siv rau lub diode. Yog hais tias lub diode rov qab biased ntawm DC, ntawm RF nws coj li tus nqi me me capacitor nrog lub peev xwm ntawm kwv yees li 1 pf.
Dab tsi yog qhov thim rov qab tsis zoo ntawm tus PIN diode?
Kev ua haujlwm tsis zoo ntawm tus PIN Diode
Thaum tus pin diode nyob rau hauv qhov kev hloov pauv tsis zoo, qhov dav ntawm thaj av depletion nce. Ntawm ib qho hluav taws xob thim rov qab, tag nrho cov txheej txheem sab hauv yuav raug tshem tawm ntawm tus neeg nqa khoom. Qhov voltage no yog hu ua swept in voltage. Tus nqi yog -2v.
PIN diodes siv rau dab tsi?
thaj chaw dav dav ua rau PIN diode ib qho tsis zoo rectifier (ib qho kev ua haujlwm ntawm diode), tab sis nws ua rau nws haum rau attenuators, ceev keyboards, photodetectors, thiab high-voltage fais fab electronics applications.
PIN diode yog dab tsi nws ua haujlwm li cas?
Tus pin diode muaj hnyav heevdoped p thiab n cheeb tsam sib cais los ntawm ib cheeb tsam intrinsic (i), raws li qhia hauv daim duab (a). Thaum reverse-biased, tus pin diode ua zoo li yuav luag tas li capacitance. Thaum mus tom ntej-kev tsis ncaj ncees, nws ua zoo li qhov tam sim no-tswj kuj sib txawv.

Kev ncaj ncees thiab kev ncaj ncees puas yog ib yam?
Nyob rau hauv Christian txoj kev ntseeg, kev ncaj ncees yog Vajtswv txoj kev ncaj ncees ntawm kev tshem tawm qhov kev rau txim, kev ua txhaum, thiab kev nplua ntawm kev txhaum, los ntawm kev tshav ntuj, thaum tib lub sijhawm, tshaj tawm tsis ncaj ncees ua ncaj ncees, los ntawm kev ntseeg Khetos txoj kev theej txhoj .
Kev tsis ncaj ncees nyob qhov twg yog qhov hem rau kev ncaj ncees nyob txhua qhov chaw?
Martin Luther King tau hais tias: “Kev tsis ncaj ncees nyob txhua qhov chaw yog kev hem thawj rau kev ncaj ncees nyob txhua qhov chaw. Peb raug ntes nyob rau hauv ib tug inescapable network ntawm kev sib nrig sib pab, khi nyob rau hauv ib lub tsoos tsho ntawm txoj hmoo.
Puas yog kev ncaj ncees sib luag lossis kev ncaj ncees?
[Equality] Kev Ncaj Ncees yog txhais tias tsuas yog los yog tsim nyog hauv qhov xwm txheej. [Fairness] Equity txhais tau tias yog qhov zoo ntawm kev ncaj ncees thiab ncaj ncees. Puas ncaj ncees txhais tias muaj vaj huam sib luag?
Puas yog kev coj ncaj ncees los siv cov ntaub ntawv sau tsis ncaj ncees?
Cov ntaub ntawv uas tau sau los ntawm kev tsis ncaj ncees tsis tuaj yeem coj ncaj ncees rov ua dua: ua li ntawd yuav tsum rov ua qhov kev sim tsis ncaj ncees. Li no, nws tsis yog kev coj ncaj ncees. Kev siv kev ncaj ncees ntawm cov ntaub ntawv txhais li cas?
Ntawm kev tsis ncaj ncees nyob qhov twg yog kev hem thawj rau kev ncaj ncees nyob txhua qhov chaw?
Martin Luther King tau hais tias: “Kev tsis ncaj ncees nyob txhua qhov chaw yog kev hem thawj rau kev ncaj ncees txhua qhov chaw. Peb raug ntes nyob rau hauv ib tug inescapable network ntawm kev sib nrig sib pab, khi nyob rau hauv ib lub tsoos tsho ntawm txoj hmoo.
