Mawonekedwe a voteji-oscillator olamulidwa amaimiridwa ndi mkhotolo (Chithunzi 1) chosonyeza mgwirizano pakati pa ma frequency aang'ono otulutsa ω0 ndi voteji yowongolera uc. Pachithunzichi, mafupipafupi a angular ω0,0 pamene uc ndi ziro amatchedwa aulere-mafupipafupi othamanga; otsetsereka K0 wa pamapindikira pa ω0,0 amatchedwa control sensitivity. Pazida zolumikizirana kapena zoyezera, voteji yolowera ndi chizindikiro chomwe chiyenera kuperekedwa kapena kuyeza (chizindikiro chowongolera).
Voltage-controlled oscillator imatchedwa frequency modulator, yomwe imagwiritsidwa ntchito kupanga ma frequency-modulated siginali. Mu ma loops odzitchinjiriza ndi gawo-zotsekeka, voliyumu yolowera ndi mphamvu ya siginecha yolakwika, ndipo voteji-controlled oscillator ndi chinthu cholamulidwa mu loop.
Mitundu ya VCO imaphatikizapo LC, RC, ndi crystal. Mfundo zazikuluzikulu zaukadaulo zama voliyumu-zowongolera ma oscillator ndi kukhazikika kwa ma frequency abwino, kutha kuwongolera kwambiri, kusinthasintha kwa ma frequency ambiri, mgwirizano wamzere pakati pa frequency deviation ndi control voltage, komanso kuphatikiza mosavuta. Magetsi a Crystal-oscillator olamulidwa amakhala ndi kukhazikika kwafupipafupi koma kusinthasintha kwafupipafupi; RC voltage-oscillator olamulidwa amakhala ndi kukhazikika kwafupipafupi koma kusinthasintha kwafupipafupi; ndi ma LC voltage-controlled oscillator amagwera penapake pakati.
