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.
