A differential type voltage-controlled oscillator circuit including: a plurality of VCO cells each having one pair of switching elements, the switching elements having one terminal side connected to a voltage source via a load and another terminal side connected to a common current source via a common node, the switching elements being supplied with differential signals, the plurality of VCO cells outputting differential signals different in phase from the differential signals; and a vibration canceling section connecting the plurality of VCO cells such that vibration at each node is cancelled. |
