Cov yam ntxwv ntawm Voltage - tswj tau oscillator yog sawv cev ntawm cov tawm tsam ω0 thiab cov tawm tswv yim tswj voltage UC. Hauv daim duab, tus lej zaus ω0,0 Thaum UC yog xoom yog hu ua lub free - khiav palistle; Txoj kab nqes K0 ntawm nkhaus ntawm ω0,0 yog hu ua tus tswj lub siab. Hauv kev sib txuas lus lossis ntsuas seev, cov tawm tswv yim tswj voltage yog lub teeb liab yuav kis lossis ntsuas (modulating teeb liab). Ib qho hluav taws xob - tswj oscillator feem ntau yog hu ua ib qho kev hloov kho thiab ntau zaus- modulated teeb liab. Hauv kev tswj hwm tsis siv neeg loops thiab theem- Cov kaw lus hluav taws xob voltage, thiab voltage- tswj cov xov tooj hluav taws xob yog ib feem ntawm lub voj.
VO HOM HOM muaj xws li LC, RC, thiab Crystal. Lub ntsiab kev xav tau rau voltage - tswj cov khoom muaj zog, kev tswj hwm siab ntawm kev sib tw ntau zaus, thiab kev tswj hluav taws xob, thiab yooj yim ntawm kev sib xyaw. Crystal voltage- tswj oscillator muaj kev loj heev tab sis ib qho nqaim zaus ntau yam; RC Voltage - tswj oscillator muaj tsawg zaus ruaj khov tab sis muaj ntau zaus cov kev hloov pauv ntau yam; thiab LC Voltage -} tswj oscillator poob ib qho nyob nruab nrab.
