Abstract
A voltage-controlled oscillator device includes first and second voltage-controlled oscillators, a first switch group including two first switches, and a second switch group including two second switches. The first voltage-controlled oscillator includes a first inductor group, a first negative resistance circuit and a first voltage output terminal group. The second voltage-controlled oscillator includes a second inductor group, a second negative resistance circuit and a second voltage output terminal group. For the first switch group, first control terminals are electrically connected to the first voltage output terminal group, first input terminals are electrically connected to the second voltage output terminal group, first output terminals are electrically connected. For the second switch group, second control terminals are electrically connected to the second voltage output terminal group, second input terminals are electrically connected to the first voltage output terminal group, second output terminals are electrically connected.
