Cov yam ntxwv ntawm varactor diode
1. Kev ua haujlwm ntawm varactor diode yog ib qho khoom siv semiconductor ua los ntawm lub hauv paus ntsiab lus ntawm qhov sib txawv ntawm qhov sib txawv ntawm PN junctions, uas yog siv los ua tus capacitor tsis sib xws hauv kev sib txuas lus siab, kev sib txuas lus thiab lwm yam circuits.
Varactor diode belongs rau qhov rov qab bias diode. Hloov qhov rov qab tsis zoo voltage ntawm PN hlws ris tuaj yeem hloov lub peev xwm ntawm PN kev sib tshuam. Qhov siab dua qhov thim rov qab, qhov tsawg dua qhov kev sib tshuam capacitance. Kev sib raug zoo ntawm qhov rov qab kev tsis ncaj ncees thiab kev sib tshuam capacitance yog nonlinear, raws li qhia hauv daim duab zoo.
2. Daim duab qhia txog kev sib raug zoo ntawm tus nqi capacitance thiab tus nqi thim rov qab ntawm varactor diode:
(a) qhov nce ntawm qhov rov qab tsis zoo voltage ua rau txo qis capacitance;
(b) txo qis ntawm qhov rov qab tsis zoo voltage, uas ua rau kom muaj peev xwm nce ntxiv.
Lub capacitance yuam kev ntau yam yog ib qho kev qhia txog kev ua haujlwm ntawm varactor diode. Cov ntawv teev cov ntaub ntawv yuav qhia qhov tsawg kawg nkaus, nominal thiab qhov siab tshaj plaws, uas feem ntau tau npaj tseg.
